Abstract: Production of a liquid crystal cell, in which 2 substrates are sealed by sealant applied around the display area, comprises (i) producing a difference in level at boundaries between the side and corner areas on one surface of a first substrate, so the corner is lower than the side; (ii) applying the sealant to these areas; (iii) pressing a 2nd substrate onto the 1st to form the hermetic seal.

Abstract: The present invention provides a method of alignment between sheet materials , a method of alignment, a substrate assembling method, and an aligning apparatus, which a re capable of easily and surely performing highly accurate alignment and suppressing a reduction in material yield. After alignment performed based on a band-like light as a reference, alignment is performed based on a joint of a condenser lens portion of a lenticular lens as a reference. More specifically, the deviation of a liquid crystal display cell in a rotational direction is corrected by using a light emitted from a light source and condensed to be band-like at the lenticular lens as a reference. Subsequently, by changing a depth of focus of a microscope, measurement is performed for positions of a black matrix of the liquid crystal display cell and the joint of the condenser lens porti on of the lenticular lens. Then, based on the result of the measurement, horizontal alignment is performed between the liquid crystal display cell and the lenticular lens.

Abstract: A liquid crystal display device comprises first and second substrates 1 and 2 disposed at a predetermined gap d1; a liquid crystal sealed in the gap d1; a seal member 4 provided at the gap d1 between the first and second substrates 1 and 2 and outside a display area 3, the seal member 4 being for sealing the liquid crystal; and a wall-like structure 5 provided outside the display area 3 and inside the seal member 4, the wall-like structure 5 being made of a material different from that of the seal member 4 and composed of a plurality of rows, effective to prevent flow of the seal material into the display area.

Abstract: Liquid crystal cell comprises a first substrate having a surface with a sealing position control structure, a seal applied on the upper side of the first substrate, and a second substrate lying above the surface of the first substrate and sealed by the seal. An Independent claim is also included for a process for the production of a liquid crystal cell comprising: (a) preparing an upper side defining the position for the seal near to the periphery along the surrounding of a surface of a first substrate, where the upper side forms a sealing position control structure; (b) applying the seal; (c) fluidizing the seal into a symmetrical shape around the center of the upper side; and (d) sealing the second substrate on the surface of the first substrate.
