Problems solved by technology

[0008] The technical problem to be solved by the present invention is to provide an effective solution for the disadvantages in the prior art that the color filter layers of different colors are arranged at intervals along the long sides of the adjacent sub-pixel opening areas, which may easily lead to light leakage from the black matrix and the occurrence of step differences between pixels. Color filter for avoiding black matrix light leakage and step difference between pixels and its manufacturing method, and correspondingly provides a liquid crystal display

Embodiment 1

[0033] In this embodiment, the color filter includes a substrate, a black matrix 101, color filter film layers of different colors, a common electrode layer and other optional layers, the black matrix 101 is arranged on the substrate and forms a grid shape, and the substrate A sub-pixel opening area 105 is formed on the upper part that is not covered by the black matrix 101. The sub-pixel opening area 105 has a long side and a short side. The sub-pixel opening areas 105 are arranged in rows along the short side direction. Color filter layers of the same color are arranged in the pixel opening area 105 to form a color filter layer row, and the color filter layer rows of different colors are arranged circularly in sequence. In this embodiment, each color filter film layer in the color filter film layer row is an integrated structure that is connected to each other and is convenient for manufacture.

Embodiment 2

[0044] The difference between the color filter in this embodiment and Embodiment 1 is that two adjacent rows of color filter layers of different colors overlap and distribute on the black matrix. Figure 4 shows that this example corresponds to figure 2 A schematic diagram of the cut plane of the color filter layer AA', wherein the red color filter layer rows formed by the arrangement of the red color filter layers 102 and the green color filter layer rows formed by the arrangement of the green color filter layers 103 are in the black matrix 101 The upper phase overlaps.

[0045] Other structures and manufacturing methods of the color filter in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

[0046] A liquid crystal display, comprising a color filter and an array substrate, the array substrate includes a plurality of parallel grid lines and data lines perpendicularly intersecting the grid lines, and the color filter adopts the color fil...

Abstract

The invention provides a color filtering sheet, comprising a substrate, a black matrix (101) and color filtering film layers with different colors. The black matrix (101) is arranged on the substrate; sub pixel opening areas (105) are formed at a place of the substrate, which is not covered by the black matrix (101); the sub pixel opening areas (105) are provided with long edges and short edges; the sub pixel opening areas (105) are arranged in line along a direction of the short edges; the sub pixel opening areas (105) in the same line are provided with the color filtering film layers with the same color, so as to form a color filtering film layer line; and the color filtering film layer lines with the different colors are sequentially and circularly arranged. The invention further provides a manufacturing method of the color filtering sheet. The color filtering sheet provided by the invention not only effectively avoids light leakage caused by shift of the color filtering film layers relative to the black matrix, but also reduces the segment difference between two adjacent pixels with the different colors on the black matrix. The conventional assembly line equipment can be directly used when the color filtering sheet is manufactured, so that the cost is low.

Description

technical field [0001] The invention relates to liquid crystal display manufacturing technology, in particular to a color filter, a manufacturing method thereof, and a liquid crystal display including the color filter. Background technique [0002] Thin Film Transistor-Liquid Crystal Display (TFT-LCD for short) panel is made up of array substrate (Array Panel) and color filter (also called color filter substrate: Color Filter Panel). Liquid crystal is injected between them to form a liquid crystal layer. [0003] In the prior art, the array substrate in TFT-LCD is provided with a plurality of parallel gate lines (gate lines) and data lines (data lines) perpendicular to the insulation of the gate lines (data lines), and the area surrounded by the gate lines and data lines is called In a unit pixel (pixel) area, the pixel electrode is arranged in the pixel area, and a thin film transistor (TFT) is arranged at the intersection of the gate line and the data line in each pixel a...
