Abstract
A method of assembling a liquid crystal display device including a pair of substrates combined together with a sealing member and a liquid crystal interposed between the substrates, includes the steps of disposing a plurality of spacers in the area of the sealing member between the substrates, positioning a frame on an outside surface of each substrate, the frame being aligned with the sealing member, and applying pressure to each frame so that a region corresponding to a display area is substantially pressure-free and a uniform cell gap is obtained.
