Abstract
A reflective display panel including a first substrate, a second substrate, a liquid crystal layer, a pixel driving layer, a color filter layer, and a polarizer. The pixel driving layer is provided with a reflective layer overlapping the color filter layer. Absorbance of a first filter pattern of the color filter layer is greater than or equal to 0.25 and less than or equal to 0.9 in a wavelength range between 530 nm and 580 nm. Absorbance of a second filter pattern of the color filter layer is greater than or equal to 0.8 and less than or equal to 1.25 in a wavelength range between 630 nm and 680 nm. Absorbance of a third filter pattern of the color filter layer is greater than or equal to 0.95 and less than or equal to 1.3 in a wavelength range between 580 nm and 630 nm.
