Claim Text:
1. A display device comprising a color filter array substrate, the color filter array substrate comprising a plurality of gate lines and a plurality of data lines disposed as intersecting each other horizontally and vertically and a plurality of pixel regions defined by the gate lines and the data lines, each of the pixel regions comprising a thin film transistor (TFT), wherein each of the pixel regions further comprises a band-pass filter layer, the band-pass filter layer transmits light within a specific wavelength range while reflects light of other wavelengths; the band-pass filter layer consists of a first medium sub-layer, a second medium sub-layer and a third medium sub-layer, the second medium layer is of different thicknesses at different pixel regions, wherein the band-pass filter layer is disposed under the TFT; an insulation layer is formed between the band-pass filter layer and the TFT, the third medium sub-layer is made of a transparent conductive material and is configured to function as a common electrode.
