Problems solved by technology

Although the latter improves the thermal stability of the photosensitive resin system, as the amount of epoxy resin added increases, the developing ability of the photosensitive resin decreases, and the light transmittance becomes poor, which in turn leads to the display effect of th

Embodiment Construction

[0011] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0012] The invention provides a photoresist composition, wherein the photoresist composition includes a resin matrix, and the resin matrix includes an acrylic resin and a phosphoric acid group-modified epoxy acrylic resin. In this embodiment, the resin matrix includes acrylic resin and phosphoric acid group-modified epoxy acrylic resin. Since the acrylic resin has a better developing effect, and the phosphoric acid group is attached to the main chain of the epoxy resin, the ep...

Abstract

The invention discloses photoresist composition and a color filter. The photoresist composition is prepared from a resin matrix which contains acrylic resin and epoxy acrylic resin modified with phosphoric acid groups. By means of the technical scheme, the photoresist composition can have better developing performance and thermal stability.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a photoresist composition and a color filter. Background technique [0002] In the manufacturing process of TFT-LCD, the main components of the photoresist for the medium color filter include the pigment or dye and the photocuring system for dyeing. The main component of the photocuring system is photosensitive resin, that is, a type of resin that can be cured and crosslinked under UV light irradiation. The function of the resin is to disperse the pigment and realize the development. In addition, the thermal stability of the resin directly affects the effect of subsequent processes and product quality. [0003] In the prior art, in order to make the photoresist have better developability and thermal stability, methods of increasing the molecular weight of certain components in the photosensitive resin or adding epoxy resin to the photosensitive resin system are u...
