Abstract

A liquid crystal display device includes a first substrate, a second substrate, a liquid crystal layer formed between the first substrate and the second substrate, and a transistor formed in a pixel. A first insulating layer is formed over the transistor, a first electrode is formed on the first insulating layer, a second insulating layer is formed on the first electrode, a second electrode is formed on the second insulating layer, and the first electrode has a plane shape and the second electrode has a line shape portion.

Claims (18)

1. A liquid crystal display device comprising:

a first substrate;

a second substrate;
