Abstract:
PROBLEM TO BE SOLVED: To provide an optical element package body and its manufacturing method, improving the rigidity shortage of an optical element while suppressing an increase in the thickness of a liquid crystal display device and suppressing the degradation of display characteristics of the liquid crystal display device. SOLUTION: The optical element package body is provided with: a film-like or sheet-like condensing element; a support body for supporting the condensing element; and a packaging member having a phase difference and wrapping the condensing element and the support body. The condensing element and the support body form a laminate, and the laminate and the packaging member are brought into close contact. The condensing element has: a base material; and a prism sequence provided on one main surface of the base material. The packaging member has: a first region to which light from a light source is incident; and a second region to which light having passed the first region is incident after passing the support body. An optical axis of the packaging member in the second region is in an oblique relationship to the ridge line of the prism sequence of the condensing element. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide an optical element inclusion body capable of reducing a positional shift between an optical element included by an inclusion member and a support body, and installed in a proper position with respect to a lighting system, a backlight and a liquid crystal display provided therewith, and a manufacturing method for the optical element inclusion body. SOLUTION: The optical element inclusion body includes the one or more of optical elements, the support body for supporting the one or more of optical elements, and the compressible inclusion member for including the one or more of optical elements and the support body. At least one hole part is provided in an peripheral edge part of an optical element laminate included by the inclusion member. The inclusion member is brought into tight contact with the optical elements and the support body, by heat treatment, while engaging a fixing member with the hole part of the optical element inclusion body, in the optical element inclusion body.

Abstract:
PROBLEM TO BE SOLVED: To provide an optical sheet laminate for preventing wrinkle, deflection and warpage while reducing the thickness and weight, and to provide a lighting unit and a display device equipped with the optical sheet laminate.SOLUTION: In the optical sheet laminate, the whole of the part facing the lower surface 20B of the optical sheet 20 in the top part 12 of the concave/convex part 11 of an optical sheet 10, and the whole of the part facing the top part of the concave/convex part 11 in the lower surface 20B of the optical sheet 20 are directly bonded (thermally welded or thermally compression-bonded). No adhesive such as an adhesive film is used for bonding the optical sheet 10 and the optical sheet 20.
Abstract:
PROBLEM TO BE SOLVED: To provide an optical packing body capable of lessening reduction of a yield caused by a position gap of an optical sheet while attaining prevention of wrinkles, bending, and a warp, thinning and weight reduction of the optical packing body, to provide a lighting device, and to provide a display device. SOLUTION: A packing film 20 covers the whole or a part of respective surfaces of a laminated body 10 such as an upper surface, a lower surface, and side surfaces, and is firmly stuck on the laminated body 10 while tension is applied in-face direction of the film. The packing film 20 is made of a light-incident side film 21 including three sheets of films 22a, 22b, 22c and a single-layered light emitting side film 22, and the films 22a, 22b, and 22c and the light emitting side film 22 are connected at a common location (connection section 20A). Diffusion sections 23, 24, 26 are formed at a range out of the films 22a, 22b, 22c opposed to an upper surface 11A of a diffusion plate 11, and a light source image adjustment section 25 is formed at a range out of the light emitting side film 22 opposed to a lower surface 11B of the diffusion plate 11.

Abstract:
PROBLEM TO BE SOLVED: To provide a laminate wherein part members are stacked with each other without using an adhesive agent nor melting the part members. SOLUTION: The laminate comprises the first part member 1 and the second part member 2, and the first part member 1 and the second part member 2 are stacked with each other. At least one stacking surfaces of the first part member 1 and the second part member 2 are subjected to a corona treatment being the ionizing radiation treatment. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide an optical element packaging body which has small dislocation between an optical element packaged with a packaging member and a supporting body and which can be set at an appropriate position against an illumination device, a backlight and a liquid crystal display device provided with the same and a manufacturing method of an optical element packaging body. SOLUTION: An optical element packaging body is provided with one or more optical elements, a supporting body to support the one or more optical elements and a contractile packaging member packaging the one or more optical elements and the supporting body. It has at least one hole part at the peripheral part of the optical element lamination body packaged by the packaging member. The optical element packaging body is obtained by carrying out a heating treatment while having a securing member engaged against the hole part of the optical element packaging body to adhere the packaging body to the optical element and the supporting body.
