Abstract

A liquid crystal display device including a pair of substrates and a liquid crystal layer sandwiched between the pair of substrates, as well as a source electrode, a Cs intermediate electrode, and a pixel electrode formed on one of the pair of substrates. The liquid crystal display device also includes vertical alignment films formed on the pair of substrates and polymer layers formed on the vertical alignment films, wherein a contact hole, which connects the source electrode and the pixel electrode, and another contact hole, which connects the pixel electrode and the Cs intermediate electrode, are both formed at a liquid crystal domain boundary.

Claims (10)

1. A liquid crystal display device comprising:

a pair of substrates;

a liquid crystal layer sandwiched between the pair of substrates;

a source electrode, a Cs intermediate electrode, and a pixel electrode formed on one of the pair of substrates;

vertical alignment films formed on the pair of substrates; and

polymer layers formed on the vertical alignment films,

wherein a contact hole that connects the source electrode and the pixel electrode and another contact hole that connects the pixel electrode and the Cs intermediate electrode are formed at a liquid crystal domain boundary.

2. The liquid crystal display device according to claim 1 , wherein:

the pixel electrode has slits, and

the liquid crystal domain boundary is formed by the slits.
