[0021] Such as Figure 2a , is a schematic cross-sectional structure diagram of the first embodiment of the liquid crystal display device of the present invention, and Figure 2b As shown, it is a schematic plan view of the first embodiment of the liquid crystal display device of the present invention. The liquid crystal display device specifically includes: a liquid crystal panel formed by a color filter substrate 1 and an array substrate 2 arranged oppositely, wherein the color filter The substrate 1 is provided with a central area 110 and a peripheral area 120, and the central area 110 and a peripheral area 120 are respectively provided with columnar spacers 5 of the same height, and the cross-sectional area of ​​the columnar spacers 5 located in the central area 110 is larger than that located in the peripheral area. The cross-sectional area of ​​the column spacer 5 in the area 120 is such that when the column spacer 5 located in the central area 110 is subjected to an ext...

Abstract

The invention relates to a liquid crystal display device which comprises a liquid crystal panel formed by an array base plate and a color filter base plate, wherein columnar spacers are additionally arranged in the center area and at least one peripheral area of the color filter base plate, and the cross-sectional area of the columnar spacer positioned in the center area is larger than that of the columnar spacer positioned in the peripheral area, so that the elastic deformation of the columnar spacer positioned in the center area under the external force is equivalent with the elastic deformation of the columnar spacer positioned in peripheral area under the external force. The invention enables the elastic forces of the columnar spacers positioned in the center area and the peripheral area under the external force to be different, thereby overcoming the defect of the prior art and improving the quality of the liquid crystal display device.

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to a liquid crystal display device which prevents light leakage through different columnar spacers. Background technique [0002] In a thin film transistor liquid crystal display (Thin Film Transistor-Liquid Crystal Display, hereinafter referred to as TFT-LCD), there are mainly two types of columnar spacers, namely columnar spacers and spherical spacers. The spherical spacers are randomly distributed on the substrate by spraying. The use of spherical spacers can reduce manufacturing costs, but the spherical spacers can only be randomly scattered on the substrate, which affects the uniformity of the cell thickness (Cell Gap), and the spherical spacers may be distributed in the pixel area. And affect the brightness of the screen. The columnar spacer is formed at the set position through a photolithography process, and the position of the columnar spacer can be controlled, which can...
