VIEWING ANGLE-CONTROLLABLE LIQUID CRYSTAL DISPLAY DEVICE AND FABRICATION METHOD THEREOF
Abstract:
A viewing angle controllable liquid crystal display device including red, green and blue color pixels and a control pixel of an electrically controlled birefringence (ECB) mode and its fabrication method are disclosed. A gate insulating layer and a passivation layer at a pixel area of the ECB control pixel are removed by using a half-tone mask to additionally secure a cell gap to thus maximize efficiency of the ECB control pixel to improve a viewing angle control effect. In addition, a light leakage is prevented by reducing a step in the vicinity of the pixel area of the ECB control pixel.
