ABSTRACT:
A VVA-mode LCD having improved transmittance and response speed includes upper and lower substrates positioned to face each other with a predetermined distance between them; a liquid crystal layer having negative anisotropy of dielectric constant interposed between the upper and lower substrates; a color resin layer formed on the inner surface of the upper substrate and having a predetermined number of valleys regularly formed inside each unit pixel; a counter electrode formed on the color resin layer including the valleys; a pixel electrode formed on the inner surface of the lower substrate and having slits arranged about the valleys of the upper substrate in a “+” shape inside and around the valleys; and alignment layers interposed between the pixel electrode and the liquid crystal layer and between the counter electrode and the liquid crystal layer, respectively.
