Title: COLOR FILTER, MANUFACTURING METHOD THEREFOR, DISPLAY PANEL, AND DISPLAY DEVICE
Abstract:
A color filter, a manufacturing method therefor, a display panel, and a display device. The color filter comprises multiple filter units distributed in an array; each filter unit comprises: a substrate (11) and a color filter layer (12) provided on the substrate (11); the color filter layer (12) comprises: a red color filter (R), a green color filter (G), a blue color filter (B), and a white color filter (W); and the areas of the red color filter (R), of the green color filter (G), and of the blue color filter (B) are greater than the area of the white color filter (W). By setting the area of the white color filter (W) as smaller than the areas of the other color filters, the aperture ratio of the white color filter (W) is reduced and, at the same time, the aperture ratios of three colors, namely red, green, and blue are adjusted, thus allowing the overall transmittance of the three colors, namely red, green, and blue, to be increased relative to the transmittance of the white color filter (W), as such, not only are the display panel and the display device ensured to provide an increased display brightness, but display color saturation also is increased, and display quality is improved.
