Problems solved by technology

Please refer to figure 1 , the half-tone mask (Half-tone ask) 1101 is a kind of gray scale mask (Gray scale mask), which is used to filter a light source 1102 and use the semi-transparent region 1103 to perform half-exposure, wherein the half-tone ask The mask in area 1103 can filter part of the light. Compared with the fully transparent area 1104, the light passing through it may only account for 5-30% of the original light. The above-mentioned method is to present the "exposed part" after one exposure process , "half-exposed part" and "unexposed part", three exposure levels, so spacers (1105, 1106) of different thicknesses can be formed on the color filter after development, wherein the substrate 1107 of the color filter There are three color filter layers on the top, which are red filter layer 1108, green filter layer 1109 and blue filter layer 1110, and between different color filter layers is a light-shielding layer composed of a black matrix. Pattern 1111, using this half-tone mask 1101 to form spacers (1105, 1106) of different heights on the light-shielding layer pattern 1111 of the color filter, wherein spacers 1105 and 1106 are formed due to different heights gap 1112; however, the half-tone mask used in the prior art is too expensive, and will not be able to save the production cost of the two substrate spacers in the manufacturing process of TFT-LCD

Embodiment 1

[0018] A schematic diagram of a preferred embodiment of the display device provided by the present invention is as follows Figure 2(a) ~ Figure 2(d) As shown, firstly, the color filter 2100 shown in FIG. Compared with the strip-shaped filter layer pattern 2101, the middle part of the island-shaped filter layer pattern (2102, 2103) is truncated and discontinuous and not interlaced with the light-shielding layer pattern 2104, that is, two islands A light-shielding layer pattern 2104 is interposed between the strip-shaped filter layer patterns (2102, 2103), wherein the strip-shaped filter layer pattern 2101 takes a green filter layer as an example, and the two island-shaped filter layer patterns (2102, 2103) are respectively colored in red Take the filter layer and the blue filter layer as an example, they are arranged circularly in the order of the colors selected above, however, any of the above filter layer patterns can be red filter layer, green filter layer, blue filter lay...

Embodiment 2

[0023] A schematic diagram of a preferred embodiment of the liquid crystal display device provided by the present invention is as Figure 3(a) ~ Figure 3(b) As shown, firstly, the color filter 3100 shown in FIG. The definition is the same as the previous embodiment, wherein the strip filter layer pattern 3101 takes the green filter layer as an example, and the two island-shaped filter layer patterns (3102, 3103) take the red filter layer and the blue filter layer as examples respectively. , arranged circularly in the order of the selected colors above, however, the pattern of the above-mentioned filter layer can be one of the red filter layer, green filter layer, blue filter layer and white filter layer, wherein the pattern of the filter layer below The light-shielding layer pattern 3104 is set, and the light-shielding layer pattern is a pattern of horizontal and vertical strips, and its function is the same as that of the previous embodiment, and the strip-shaped filter layer...
