ABSTRACT:
A liquid crystal display device including a first substrate, a second substrate, and a sealing member for bonding the first and the second substrates, wherein a spacer for determining a thickness of a gap between the first and the second substrates is included only in the sealing member and wherein d<D where D is the thickness of the gap and d is the thickness of the sealing member. The gap is filled with a liquid crystal. A method for producing a liquid crystal display including the steps of pressing a liquid crystal panel including a first substrate and a second substrate interposing a sealing member which contains a spacer mixed therein, the spacer determining a thickness of a gap between the first and the second substrates, in a state where an elastic sheet having a cutout corresponding to the liquid crystal panel is provided a surface of one of the first and the second substrates, the surface being out of contact with the sealing member; curing the sealing member; and injecting a liquid crystal into the gap.
