ABSTRACT:
In a liquid crystal display device including an array substrate which is provided with contact holes and a counter substrate which is provided with integral spacers and aligned with the array substrate, an overall region including every pixel region is divided into a plurality of subregions, each of which includes two or more said spacers and is composed of at least one said pixel region. The spacers are so arranged that when one or some of the spacers are positioned to get into the corresponding contact holes, the rest of the spacers are positioned off the corresponding contact holes. By so doing, a uniform gap is provided between the substrates even if accuracy in aligning the substrates with each other is not considerably high.
