Title: COLOR FILM SUBSTRATE AND PREPARATION METHOD THEREFOR, AND DISPLAY DEVICE
Abstract:
A color film substrate and a preparation method therefor, and a display device. The color film substrate (10) comprises: a first substrate (11) and a color film layer (12) formed on a first surface (11a) of the first substrate (11); multiple kinds of transmissive patterns (P) being distributed systematically on the color film layer (12), each kind of transmissive pattern (P) being formed by systematically arranging wavelength holes (H) with one range of hole diameters, and each kind of the transmissive patterns (P) transmitting light of one color. After lights from a backlight source (30) pass through the color film layer (12), the lights of different colors are transmitted through the wavelength holes (H) with different ranges of hole diameters, such that the lights of each color have excellent transmittance, thereby improving the display effect.
