Embodiment Construction

[0028] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0029] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as...

Abstract

The invention relates to a color filter and a liquid crystal display device. The color filter comprises a first substrate and a second substrate; the first substrate comprises a first underlayer, a first photoresist layer and a color filter layer, the first photoresist layer is arranged on the first underlayer and provided with a plurality of parallel filter grooves formed at intervals, the colorfilter layer comprises a plurality of filter units, and the filter units are arranged in the filter grooves in a one-to-one correspondence mode. The second substrate comprises a second underlayer anda second photoresist layer, and the second photoresist layer is arranged on the second underlayer and provided with a plurality of strip-shaped hollowed-out patterns which are arranged in parallel atintervals; the face where the second photoresist layer of the second substrate is located is connected with the face where the first photoresist layer of the first substrate is located, and the strip-shaped hollowed-out patterns and the filter grooves are perpendicularly arranged in an intersecting mode. According to the color filter, the manufacturing and assembling difficulty of the photoresistlayers is reduced, the light leakage phenomenon of the liquid crystal display device can be reduced through the cooperation of the first photoresist layer and the second photoresist layer, and the display contrast ratio of the liquid crystal display device is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a color filter and a liquid crystal display device. Background technique [0002] Liquid crystal display devices such as liquid crystal televisions are one of the most widely used flat panel displays at present, and the liquid crystal display panel is its core component. Traditional liquid crystal display devices use blue LEDs coated with yellow phosphor as white backlight. In order to display color images, liquid crystals and color filters are also required. However, the current color filter has the problems of light leakage and low display contrast, so it needs to be improved. Contents of the invention [0003] Based on this, it is necessary to provide a color filter and a liquid crystal display device capable of reducing light leakage and improving display contrast. [0004] A color filter comprising: [0005] The first substrate includes a first substrate, a first phot...
