Embodiment Construction

[0021] In order to make the above content of the present invention more comprehensible, preferred embodiments are specifically cited below for detailed description.

[0022] The present invention will provide many different embodiments to implement different features in the present invention, but it is not intended to limit the present invention, anyone with ordinary knowledge in the technical field will not depart from the spirit and scope of the present invention , can be modified and retouched arbitrarily.

[0023] The invention provides a color photoresist composition, in which a sandwich-type phthalocyanine compound is added as a dye. Because the dye has high thermal stability and high solubility, it can effectively relieve pigment particles in the photoresist. Scattering of light, thereby improving the transmittance and contrast of the color filter.

[0024] Accordingly, according to an embodiment of the present invention, the present invention provides a color photores...

Abstract

The invention provides a colored photoresist composition. The colored photoresist composition comprises in parts by weight based on 100 parts: 5-10 parts of pigment dispersion; 5-8 parts of binder resin; 5-8 parts of a sandwich type phthalocyanine compound dye; 0.3-0.8 parts of a photoinitiator; 70-85 parts of a photoresist solvent; and 0.1-0.2 parts of an additive.

Description

technical field [0001] The invention relates to a color photoresist composition, in particular to a color photoresist composition capable of alleviating the light scattering effect of the photoresist. Background technique [0002] Color filter (Color Filter, CF) is an important source of liquid crystal display (Liquid Crystal Display) display color; and color photoresist is an important part of color filter (Color Filter), which can be divided into red (R) , green (G), blue (B) three types. The current color filter photoresist generally achieves its hue by adding different colored pigments (Pigment), wherein the pigment (Pigment) is an insoluble substance, which is usually added to the substrate in a highly dispersed state to color the substrate. The dispersed particles of the pigment have a serious scattering effect on light, which will reduce the transmittance and contrast of CF. [0003] In order to improve the transmittance and contrast of the color filter, a new color...
