Embodiment Construction

[0025] see Figure 6 , is a schematic plan view of the first embodiment of the color filter of the present invention. The color filter 100 of the present invention includes a plurality of pixels 101, and each pixel 101 includes three sub-pixels of red, green and blue, and the sub-pixels are arranged continuously in an S-shaped structure.

[0026] Since the sub-pixels are arranged in an S-shaped structure, for a certain area IV, the area IV is a rectangle with a length of L and a width of W, the sub-pixel S-shaped amplitude is A, and the amplitude A is W / 2, so the area IV It includes not only the main primary color (blue), but also the secondary primary colors (green and red), and the ratio of the area occupied by the primary primary color to the secondary primary color in area IV is 0.682:0.318, so for this area IV, it will Color mixing occurs, and the IV color display effect in this area is better. Similarly, for other areas, the color display effect is also better. Theref...

Abstract

A colour filter consists of multiple image elements as each image element includes three sub - image elements of red, green and blue; the sub - image element includes two parts being bended towards to different directions or partially being prepared in arc form. The liquid crystal display unit consists of two substrates being set oppositely, a liquid crystal layer between above two substrates and a colour filter set on either of two substrates.

Description

【Technical field】 [0001] The invention relates to a color filter and a liquid crystal display device using the color filter. 【Background technique】 [0002] The liquid crystal display device is a passive display device. In order to achieve the effect of color display, a color filter needs to be provided for it. Different color images are displayed by other components such as liquid crystals. [0003] see figure 1 , is a schematic plan view of a prior art color filter. The color filter 1 includes a plurality of pixels arranged in order, and each pixel includes three sub-pixels of red (R), green (G), and blue (B), and the sub-pixels are arranged as shown in the first figure Stripe structure. The color filter structure is relatively simple, and for a certain area I, the area I is rectangular, its length is L, and its width is W, then only one primary color is included in the area I, so when it is applied to a liquid crystal display device , the color mixing effect is poor,...
