TFT-LCD WITH WIDE VIEWING ANGLE

机译:TFT-LCD具有宽视角

摘要

The present invention relates to a TFT-LCD having an expanded viewing angle in which rubbing is performed by forming a double alignment layer having different pretilt angles in one pixel in order to extend the viewing angle.;The present invention provides a liquid crystal generated by opposing the color filter substrate and the TFT substrate by etching the color filter substrate and the alignment layer formed on the TFT substrate opposite thereto to form a dual alignment layer, and etching the upper alignment layer to have a predetermined width in a diagonal direction. When an observer looks at an area having a different tilt degree, since the average optical characteristic of the area is recognized, there is an advantage in that a TFT-LCD having a wide viewing angle without a phenomenon such as brightness inversion at the left and right and up and down angles can be realized.;In addition, since the direction of the liquid crystal is reversed, the generated declining can be reduced, thereby reducing the width of the black matrix blocking the leakage light leaked between the pixels, thereby improving the aperture ratio. .
