Abstract

The invention provides a green photoresist material, an LCD panel and a preparation method of the green photoresist material. The green photoresist material is a phthalocyanine molecule, and one substituent group of the phthalocyanine molecule is a dendritic compound; the steric hindrance of substituent groups of the dendritic compound is large, so accumulation and aggregation of phthalocyanine molecules due to strong pi-pi acting force can be hindered; the substituent group of the dendritic compound is amphiphilic, so that the solubility of the phthalocyanine molecule is improved, and the problem that athe photoresist material is prone to remaining during development is solved; and the single-molecular-state and high-solubility phthalocyanine molecule can avoid stray light introduced by the light scattering problem, so the penetration and contrast of color resistance are greatly improved. The green photoresist material has the characteristics of high solubility, high penetration, goodthermal stability and self-development, and can be applied to the LCD panel to improve the brightness and contrast of the display panel and relieve the problems of insufficient brightness and contrast of the existing LCD panels.

Description

Technical field [0001] This application relates to the field of display, in particular to a green photoresist material, an LCD display panel and a preparation method. Background technique [0002] Liquid Crystal Display (LCD) technology is a passive light-emitting mode, and its color reproduction ability is mainly reproduced by the backlight through the color filter. Under the current needs of high brightness, wide color gamut, and high contrast, the color film The development demand is getting higher and higher. In particular, green photoresist has the greatest impact, because the visual function of the human eye shows that vision is most sensitive to green, so a slight increase in green light will greatly contribute to the overall improvement of LCD penetration. [0003] However, due to the large size of the traditional pigment particles, the scattering effect is obvious, which leads to low utilization rate of the backlight, reduced brightness and contrast, and no longer meets t...
