ABSTRACT:
A liquid crystal display apparatus includes first and second substrates, a fence, a liquid crystal layer and a plurality of spacers. The first substrate includes a display region for displaying an image. The second substrate faces the first substrate. The fence is disposed between the first substrate and the second substrate. The fence surrounds the display. The spacers maintain the distance between the first and second substrates. The spacers have a gradually increasing compression ratio in a direction from a center of the display region to an edge of the display region. The liquid crystal display apparatus maintains a uniform cell gap, even though a compressive stress of a center portion of the liquid crystal display apparatus is different with a compressive stress of an edge portion of the liquid crystal display apparatus. Therefore, display quality is enhanced.
