Embodiment Construction

[0029] The color photoresist compositions according to the embodiments of the disclosure have better dielectric constant stability, so that the fabricated photoresist layer has better electrical properties. The composition proposed in the embodiment is for the purpose of illustration, and is not intended to limit the scope of protection of the content of the present invention. Those skilled in the art may modify or change these compositions according to the needs of actual implementation.

[0030] The "permittivity loss rate" described in this article indicates the ratio of the numerical difference between the two dielectric constants measured at different operating frequencies. For example, the calculation method of "permittivity loss rate (20-1000Hz)" is: ( (dielectric constant (1000Hz)-dielectric constant (20Hz)) / dielectric constant (1000Hz), where the dielectric constant (1000Hz) represents the dielectric constant measured when the operating frequency of these materials is...

Abstract

The invention discloses a color photoresist composition and a detection method of dielectric constant loss ratio thereof. The color photoresist composition comprises a red material, a resin material, a photopolymerizable monomer and a light initiator, wherein the resin material is a first copolymer or a second copolymer, the first copolymer comprises tricyclodecyl methacrylate, benzene and acrylic acid, the second copolymer comprises epoxy dicyclopentenyl acrylate, dicyclopentenyl acrylate, vinyl toluene and acrylic acid, the weight proportion of the resin material relative to the sum of the resin material and the photopolymerizable monomer is larger than or equal to 30wt%, and the light initiator comprises an oxime light initiator. The color photoresist composition has relatively excellent dielectric constant stability, and thus, a photoresist layer fabricated from the color photoresist composition has relatively excellent electrical property.

Description

technical field [0001] The invention relates to a color photoresist composition and a method for detecting its dielectric constant loss rate, in particular to a color photoresist composition used for a color filter layer and a method for detecting its dielectric constant loss rate. Background technique [0002] A color liquid crystal display device uses a color filter layer to present a color display image, and the optical properties of the color filter layer have a key influence on the optical display effect of the color liquid crystal display device. The color filter layer includes photoresist layers of different colors. [0003] When the operating frequency of the display device changes, the photoresist layer material may disintegrate due to the change of the operating frequency based on its own characteristics, so that the dielectric constant decreases with the change of the operating frequency, thereby affecting the electrical properties of the display device. have adv...
