Problems solved by technology

Due to the lack of precision and deviation in the production process of the mask plate in the prior art, its exposure precision can only reach the micron level and cannot reach the nanometer level. Therefore, the color filter substrate formed by the above-mentioned process does not have polarization ability. It is also necessary to attach a polarizer with polarizing ability
This process of making color filter substrates is cumbersome, time-consuming, and labor-intensive.

Embodiment Construction

[0033] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0034] Such as figure 2 Shown is a flowchart of a method for manufacturing a color filter according to an embodiment of the present invention, including:

[0035] Step 1. Form an intermediate layer for forming a black matrix on the substrate;

[0036] The substrate may be a glass substrate. In this embodiment, the intermediate layer is a metal layer, specifically aluminum, or chromium, or gold or silver. The intermediate layer may also be a resin layer containing a conductive substance, and the conductive substance may be Nano-scale metal wires, such as silver wires, aluminum wires, etc.; or metal powder additives, so that the subsequently formed polarizing layer has certain electromagnetic characteristics. The i...

Abstract

The invention relates to the technical field of LCD (liquid crystal display) monitors and in particular discloses a color filter with polarization ability and a manufacturing method thereof. The manufacturing method of the color filter includes the following steps: step 1, forming an intermediate layer on a substrate; step 2, forming photoresist on the intermediate layer; step 3, forming nanometer grating patterns on the photoresist; step 4, etching the photoresist with the nanometer grating patterns until a black matrix and a polarizing layer provided with grating patterns are formed on the intermediate layer. According to the invention, the polarizing layer with polarization ability is formed at the same time the black matrix is formed. Therefore, the step of attaching a polarizer is omitted while the display effect of a monitor is ensured, the time of the manufacturing process is saved and the cost is reduced.

Description

Technical field [0001] The present invention relates to the technical field of liquid crystal displays, in particular to a color filter manufactured by using a nanoimprint method, and a manufacturing method of the color filter. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD) is currently the mainstream of flat panel displays, which has the advantages of low power consumption, relatively low cost, and basically no radiation. The principle is to use the dielectric anisotropy and conductive anisotropy of the liquid crystal molecules to switch the alignment state of the liquid crystal molecules when an electric field is applied, causing the liquid crystal film to produce various photoelectric effects. [0003] The TFT LCD panel is formed by aligning a color film substrate and an array substrate. Such as figure 1 As shown, it is a cross-sectional view of a color filter substrate in the prior art. In the TFT-LCD production process, the following metho...
