Manufacturing method of display device and color filter thereof

Abstract

The invention provides a manufacturing method of a display device and a color filter thereof. The display device comprises a first substrate, a second substrate and a first cushion, wherein multiple filter layer patterns are arranged on the first substrate, and a shading layer pattern is arranged below every two adjacent filter layer patterns; the filter layer patterns include strip-type filter layer patterns and island-type filter layer patterns; the second substrate is arranged opposite to the first substrate; the first cushion is provided with a first end and a second end, the first end makes contact with the second substrate, and the second end makes contact with the strip-type filter layer patterns.

Description

technical field [0001] The present invention relates to a display device, in particular to a display device which utilizes the structure and material properties of the color filter to form the height difference of spacers on the color filter. Background technique [0002] Liquid crystal display (LCD) has been widely used in display devices of electronic products due to its advantages of light and thin volume, low power consumption, low operating voltage and high image quality, while thin film transistor liquid crystal display (Thin film transistor liquid crystal display) crystal display, TFT-LCD) is one of most liquid crystal displays, which uses thin film transistor technology to improve image quality, and is used in TVs, mobile phones, notebook computers, tablet computers, desktop computers, projectors and other display devices, etc. Consumer electronics or computer products. The structure of the TFT-LCD panel is that a layer of liquid crystal is sandwiched between two gl...

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
