Color filter array substrate and liquid crystal display panel

Abstract

The invention discloses a color filter array substrate which comprises a glass substrate body, a first metal layer, an insulation layer, an active layer, an ohmic contact layer, a second metal layer, a first passivation layer, a color filter layer, a second passivation layer and a pixel electrode layer. A channel is formed in the color resistance overlapping position of the color filter layer, a public electrode wire is arranged on the first metal layer corresponding to the channel in the Y-axis direction, a metal wire is arranged on the second metal layer corresponding to the channel in the X-axis direction, and therefore light shielding is achieved. According to the color filter array substrate, not only can leak light be effectively shielded, but also circulation of PI and liquid crystals can be improved.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a color filter array substrate and a liquid crystal display panel. 【Background technique】 [0002] The application of BCS / BMless technology on the LCD panel can reduce the use of a BM and save costs. BCS (blackcolumnspace) technology uses black materials. The function of using black material is on the periphery, which can directly replace BM with black material to play the role of shading, and another function is to support the thickness of the box in the AA area. Shading the scan line (gate) and data line (data) in the AA area needs to rely on color-resist stacking and metal interaction to achieve. Color resistance overlap generally uses red and blue overlap, because the spectrum of the two colors does not intersect, the light effect is better. [0003] BCS / BMless technology The products already on the market currently use IPS technology. IPS technology uses a planarizati...

Problems solved by technology

[0005] The purpose of the present invention is to provide a color filter array substrate and a liquid crystal display panel, aiming to solve the problem of a four-sided protrusion in the place where the color resists overlap in the BCS / BMless technology under the HVA mode existing in the prior art, During the process of PI coating and liquid crystal dripping, the uneven flow of PI and liquid crystals will occur due to the raised walls on all sides, which will affect the display effect.
