Abstract

The invention relates to the technical field of liquid crystal display and discloses a preparation method of a colorful substrate. The preparation method comprises preparing a mask plate of a black matrix and setting specific unthreaded hole filling patterns on the mask plate of the black matrix aiming at sub-pixels in specific colors; preparing a mask plate of a colorful film and arranging light penetration holes in same size on the mask plate of the colorful film aiming at sub-pixels in different colors; enabling the positions of the light penetration holes to correspond to those of the unthreaded hole filling patterns; and preparing the colorful substrate by using the mask plate of black matrix and the mask plate of the colorful film. The invention further discloses the colorful substrate and a semi-reflection semi-penetration liquid crystal display device, can prepare red, green and blue sub-pixel colorful film layers with different light penetration hole sizes by using one mask plate of the colorful film, accordingly guarantees display effects while reducing production cost of the colorful substrate when the colorful substrate is applied to a display device.

Description

Technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to a preparation method of a color filter substrate, a color filter substrate and a semi-reflective and semi-transparent liquid crystal display device. Background technique [0002] In recent years, liquid crystal displays (such as TFT-LCD) have been increasingly used in outdoor mobile products, such as mobile phones, PDAs, and tablet computers. However, when ordinary liquid crystal display devices are used in outdoor sunlight, the contrast is poor, which makes the screen readability poor. The transflective liquid crystal display can increase the contrast of the display device during outdoor display by increasing the reflectivity of the panel, so that the display can maintain excellent readability even outdoors. [0003] There are transmissive parts and reflective parts in the pixels of the transflective liquid crystal display, and its structure is as figure 1 Shown...
