Abstract: A support structure (3) for supporting a display apparatus (2) which can be tilted vertically upwards or downwards from a predetermined position, is disclosed. This support structure has a tilting mechanism (10) providing a differential torque reaction to an applied tilting force to accommodate a difference in the applied torques required when tilting upwards against the weight of the display apparatus (2) and when tilting downwards assisted by the weight of the display apparatus (2), respectively. In the preferred arrangement, the differential torque reaction is provided by a fixed helical spring (13) and a horizontal axis member (12) at each end (10r,10l) of a support arm (8) provided for supporting the display apparatus (2) on the support structure (3).

Abstract: A liquid crystal display apparatus is constituted by: a housing; a liquid crystal panel comprising a liquid crystal disposed between a pair of substrates each provided with electrodes, the liquid crystal panel being affixed to the housing; and a backlight for illuminating the liquid crystal panel, detachably affixed to the housing. A light-transmissive plate, such as a diffusion plate, allowing transmission of light from the backlight is further disposed between the liquid crystal panel and the backlight so as to define an almost closed first space in cooperation with the liquid crystal panel, whereby the first space retaina its almost closed state even when the backlight is detached from the housing.

Abstract: A display apparatus is constituted by a display panel having an electrode terminal, a flexible carrier carrying a drive element for driving the display panel together with an input terminal and an output terminal connected thereto, a circuit board for supplying signals to the drive element, and a support plate for supporting the display panel and the circuit board. The output terminal and the input terminal of the flexible carrier are connected to the electrode terminal of the display panel and the circuit board, respectively. The support plate is provided with a supporting member, for supporting the circuit board at a position which is farther from the display panel than a line dividing the circuit board into equal halves closer to and farther from the display panel. As a result, when the display apparatus is supplied with an impact in a direction perpendicular thereto, the circuit board is allowed to rotate so as to reduce a stress applied to the flexible carrier, thereby preventing the breakage or electrical connection failure thereof.

Abstract: A liquid crystal apparatus includes: a liquid crystal panel (101), an illumination means (109) for illuminating the liquid crystal panel, a supporting means (104,107) for supporting the liquid crystal panel and a housing (108) for housing the above members. The liquid crystal panel and the supporting means are arranged so as to define an almost closed space (124) functioning as an air damper to suppress deformation caused by an externally applied force owing to elasticity of air within the almost closed space. The supporting means includes a unit-supporting portion (107) for supporting the illumination means, the unit-supporting portion being provided with a cutout (122) at a part thereof for promoting discharge of heat evolved from the illumination means, and, the illumination means is supported by the unit-supporting portion so as to stop up the cutout of the unit-supporting portion, thus retaining the almost closed space. The liquid crystal apparatus is further provided with means (125) for enhancing discharge of heat evolved by the illumination means out of the apparatus from a side opposite to the liquid crystal panel of the illumination means.
