Abstract

A liquid crystal display device which is resistant to physical impact and can retain high-quality display characteristics is provided. Further, a liquid crystal display device with high reliability and high performance is provided. In a liquid crystal display device in which a liquid crystal composition is interposed between a pair of substrates, a spacer for keeping a gap between the substrates is provided over a structure body provided under a pixel electrode layer or a common electrode layer. The structure body is provided to make the pixel electrode layer and the common electrode layer project into the liquid crystal composition, and the structure body is provided to extend to a region where the spacer is provided. Since the structure body is formed using one continuous film, regions of the surface thereof have substantially the same height and the spacer can be stably provided with good adhesion.

First claim

What is claimed is:

1. A liquid crystal display device comprising:
a first substrate and a second substrate with a liquid crystal composition interposed therebetween;
a first structure body projecting into the liquid crystal composition from a surface of the first substrate on a liquid crystal composition side;
a second structure body provided between a first region and a second region of the first structure body and projecting into the liquid crystal composition from the surf…
