Abstract
Provided is a display panel, including an array substrate, a color filter substrate, and a back light module. The back light module includes a light source, and the light emission spectrum of the light source has a first blue peak and a second blue peak. The color filter substrate is provided with multiple pixel units which are periodically and repeatedly disposed, and at least one pixel unit includes a red sub-pixel, a green sub-pixel, a first blue sub-pixel and a second blue sub-pixel. The first blue sub-pixel and the second blue sub-pixel have different transmittance spectrums; a peak wavelength of a transmittance spectrum of the first blue sub-pixel matches a peak wavelength of the first blue peak of the light source, and a peak wavelength of a transmittance spectrum of the second blue sub-pixel matches a peak wavelength of the second blue peak of the light source.
