Problems solved by technology

[0006] However, when the color filter 12 is subjected to collision or other abnormal forces during the manufacturing or handling process, the spacer 121 directly presses the conductive layer 123, causing the conductive layer 123 to be broken and damaged, resulting in a ring mura phenomenon. , so that the overall production quality is not good, leading to a decline in product reliability
[0007] In view of this, there is an urgent need to develop a new structure and manufacturing method of color filters, in order to improve the problem of cracking and damage caused by spacers directly pressing the conductive layer, thereby improving the production quality of liquid crystal display modules

Embodiment Construction

[0049] Hereinafter, the color filter and the manufacturing method thereof according to the preferred embodiment of the present invention will be described with reference to related drawings.

[0050] See image 3 , Is a color filter according to a preferred embodiment of the present invention, which includes a color filter substrate 21, a conductive layer 22, and a spacer 23. In this embodiment, the color filter is applied to the liquid crystal display module.

[0051] The color filter substrate 21 has a light shielding layer 211 and a color filter layer 212. The light-shielding layer 211 is a black matrix (BM), and the material of the black matrix may be resin, chromium, chromium oxide, or chromium oxynitride. In this embodiment, the color filter substrate 21 further includes a substrate 213. The light shielding layer 211 and the color filter layer 212 are disposed on the substrate 213, and the color filter layer 212 covers a portion of the light shielding layer 211. Of course, s...

Abstract

The present invention discloses a colorful optical filter which comprises a colorful optical filtering substrate, a conducting layer and a spacer. The colorful optical filter is provided with a shading layer and a colorful filtering layer. The conducting layer is provided on the colorful optical filtering substrate, and the conducting layer is provided with at least one opening at the position relative to the shading layer and / or colorful filtering layer. The spacer is provided in the opening. The invention also discloses a method for preparing the colorful optical filter.

Description

Technical field [0001] The invention relates to a color filter, in particular to a color filter capable of avoiding black pill phenomenon and a manufacturing method thereof. Background technique [0002] Generally speaking, in order to achieve display characteristics such as fast response speed, high contrast, and wide viewing angle of the liquid crystal display module, the liquid crystal display module used must strictly maintain the uniformity of thickness. [0003] See figure 1 , Is a known liquid crystal display module 1, which usually has a transistor (TFT) substrate 11 and a color filter 12 oppositely arranged, and a space is formed between the transistor substrate 11 and the color filter 12 ( cell gap) 13. The space 13 is used to fill liquid crystal L. In addition, the color filter 12 has a plurality of spacers 121. Each spacer 121 keeps the distance between the transistor substrate 11 and the color filter 12 and prevents The liquid crystal display module 1 leaks light. ...
