[0043] figure 2 Schematic diagram of the structure of the color filter substrate provided by Embodiment 1 of the present invention; image 3 A cross-sectional view of a black matrix layer and a color filter layer in a color filter substrate provided in Embodiment 1 of the present invention. Such as figure 2 with image 3 As shown, the color filter substrate 100 provided in this embodiment includes: a base substrate 101, a black matrix layer 102 and a color filter layer 103 disposed on the base substrate 101, and the color filter layer 103 includes a first filter Layer 1031, the second filter layer 1032 and the third filter layer 1033, the first filter layer 1031, the second filter layer 1032 and the third filter layer 1033 all have extensions extending toward the outside of the black matrix layer 102 1034 , the width of the extension portion 1034 is smaller than the width of any one of the first filter layer 1031 , the second filter layer 1032 and the third filter layer 1...
Embodiment 2
[0058] Figure 4 It is a flow chart of the manufacturing method of the color filter substrate provided in the second embodiment of this embodiment. Such as Figure 4 As shown, this embodiment provides a method for manufacturing the color filter substrate of the above embodiment, including the following steps;
[0059] In the first step, a black matrix layer 102 is formed on the base substrate 101 .
[0060]It should be noted that, before forming the black matrix layer 102 on the base substrate 101 , it needs to be cleaned by a cleaning machine.
[0061] Specifically, forming the black matrix layer 102 on the base substrate 101 may be:
[0062] Sputtering a black film on the base substrate 101, the black film is mainly a black pigment film;
[0063] Coating photoresist on the black film and pre-baking to form a photoresist layer;
[0064] The photoresist layer is exposed and developed sequentially,
[0065] Etching the black film according to the development result; and ...
Embodiment 3
[0080] Figure 5 A schematic structural diagram of a liquid crystal display panel provided in Embodiment 3 of this embodiment. Such as Figure 5 As shown, this embodiment provides a liquid crystal display panel, including: the color filter substrate 100 provided in the above embodiment.
[0081] Specifically, the liquid crystal display panel includes a color filter substrate 100 , an array substrate 200 , and a liquid crystal molecule layer 300 located between the color filter substrate 100 and the array substrate 200 . Specifically, the color filter substrate 100 is disposed opposite to the array substrate 200 , and the liquid crystal molecule layer 300 is located between the color filter substrate 100 and the array substrate 200 .
[0082] Wherein, the color filter substrate 100 adopts the color filter substrate 100 provided in the above embodiments.
[0083] The structure and working principle of the color filter substrate 100 have been described in detail in the above-m...
