Title:
ACTIVE MATRIX COLOR LIQUID CRYSTAL DISPLAY
Document Type and Number:
Japanese Patent JPH0534680
Kind Code:
A
Abstract:
PURPOSE:To suppress the deterioration of the display quality caused by an orientation failure of a liquid crystal molecule generated due to a step difference of a color filter substrate by forming a color layer of a color filter to continuous patterns in the vertical direction. CONSTITUTION:A color array runs along a source wiring 6 and it is called a as vertical stripe array. Color layer patterns 1, 2 and 3 of R, G and B become continuous patterns. Since the color layer patterns 1, 2 and 3 become the continuous patterns in the vertical, direction, there is no step difference of a color filter substrate in the direction running along a gate wiring 5. In order to cut off a leakage light of the outside of a display electrode 4, a step difference of a pattern called a black matrix 7 exists along the gate wiring 5, but since the color layer patterns 1, 2 and 5 are formed by applying an organic molecule, the step difference of the black matrix 7 is flattened and becomes that which has no problem. Accordingly, since a step difference running along the gate wiring which is apt to cause a liquid crystal orientation failure is not generated, a stable liquid crystal orientation is obtained.
