Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. The following examples are only used to illustrate the present invention, but should not be used to limit the scope of the present invention.

[0029] see image 3 , is a schematic structural view of a liquid crystal panel with a color filter substrate of the present invention. In this embodiment, the liquid crystal panel includes an active matrix substrate 31, a color filter substrate 32, and a substrate clamped between the active matrix substrate 31 and the color filter substrate. The liquid crystal layer 33 between the optical sheet substrates 32 .

[0030] The active matrix substrate 31 and the color filter substrate 32 are disposed opposite to each other, and include a transparent substrate, driving wiring and an alignment layer disposed on the transparent substrate. Since the active matrix substrate 31 used in the present invention is th...

Abstract

The invention discloses a color filter substrate and a manufacturing method for the same. The method comprises the following steps of: forming a black matrix pattern in a pixel ineffective area of a transparent substrate to form a mark; coating a transparent conductive layer on the pixel inactive area to cover the mark; and patterning the transparent conductive layer to make the covering characteristics of the transparent conductive layer at the mark and the peripheral zone of the mark different. Optical differences of the mark and the peripheral zone of the mark under a charge coupled device (CCD) optical pickup lens are effectively enhanced, and the success rate of the pickup of the mark is increased, so that production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a color filter substrate and a manufacturing method thereof. Background technique [0002] In the liquid crystal panel manufacturing process, the alignment mark (mark) plays an important role. When position confirmation and coordinate calculation are required, the position of the alignment mark needs to be read. For example, when performing coordinate positioning of precision measuring instruments and exposure alignment of exposure machines, it is necessary to read the position of the alignment marks; Confirm the group position of the substrate. [0003] see figure 1 , figure 1 It is a schematic diagram of setting the alignment mark on the existing color filter substrate. [0004] Such as figure 1 As shown, in the prior art, the transparent substrate 10 of the color filter substrate includes a plurality of effective pixel regions 100 and invalid pixel regions ...
