Abstract
In a lateral electric field liquid crystal display device, a major electrode portion for generating a lateral electric field is formed using a layer different from a layer on which other electrodes and lines are formed. In this case, the major portion is formed to have a thickness of {fraction (1/20)} to ⅓ of the thickness of each of the other electrodes and lines. Thus, flatness of a base film of an alignment layer is significantly improved, also alignment layer material can be coated and formed with high flatness on the base film, and rubbing of the alignment layer material can be performed uniformly for the overall substrate surface.
Claims8
A lateral electric field liquid crystal display device comprising:
- a TFT substrate provided with a signal line, a common line, a pixel electrode and a common electrode, said pixel electrode being partially formed in a layer different from and above said signal line and said common line, said common electrode being formed in said layer;
- said common electrode and a portion of said pixel electrode formed in said layer being formed thinner than said signal line and said common line;
- an opposing substrate;
- and
- a liquid crystal layer sandwiched between said TFT substrate and said opposing substrate,
- said TFT substrate including.
