Patent ID: 8670089

Claim:
A display device, comprising: a blue light source; and a display panel disposed on the blue light source, wherein the display panel comprises: a substrate; a color adjusting layer formed on the substrate facing the blue light source, wherein the color adjusting layer comprises a plurality of color excitation units, each color excitation unit comprises a plurality of wavelength transformation materials; a blue filter layer formed on the color adjusting layer facing the blue light source, wherein the blue filter layer allows blue light to pass therethrough and absorbs non-blue light; and a polarizer layer formed on the blue filter layer facing the blue light source, wherein blue light emitted from the blue light source reaches the color adjusting layer through the polarizer layer and the blue filter layer, part of the blue light excites the wavelength transformation materials of the color excitation units to generate non-blue light, part of the non-blue light is transmitted to and absorbed by the blue filter layer to reduce the performance of non-blue color in the color adjusting layer.
