Abstract: The present invention relates a red color filter photoresist. The present invention adopts rhodamine and its derivatives with high dye uptake as a red dye, in combination with red and yellow pigment systems, to form a mixed dye-pigment red color filter photoresist that satisfies current requirements of wide color gamut and processing requirements of LCDs, which prevents that development of red color filter photoresist stagnates and leads to problems of products such as white points and dark state color points, and is advantageous to realize a liquid crystal display with wider color gamut.

Abstract: A manufacturing method of a rhodamine dye oligomer, a solid color material, and a liquid crystal display device are provided. By oligomerization of rhodamine dyes, monodispersion of rhodamine dyes can be achieved, preventing the enhanced shoulder peak caused by aggregation of rhodamine dye molecules, Meanwhile, the purification of color gamut is achieved, and the thermal stability of rhodamine dyes is increased, thereby meeting the need of liquid crystal display devices. Moreover, applying the rhodamine dye oligomer to the solid color material and fabricating the solid color film for application in the liquid crystal display devices can prevent a great loss of brightness of display devices.
