Claim:
1. A color filter substrate, comprising: an underlying substrate; a semi-transparent and semi-reflecting layer formed on the underlying substrate; and a black matrix and a color filter layer formed on the semi-transparent and semi-reflecting layer, wherein the black matrix and the color filter layer are formed on a side of the semi-transparent and semi-reflecting layer away from the underlying substrate; wherein the semi-transparent and semi-reflecting layer comprises a first region on which the black matrix is formed and a second region on which the color filter layer is formed, and a light reflectivity of the first region is larger than a light reflectivity of the second region; wherein the semi-transparent and semi-reflecting layer comprises a reflective film; wherein a light reflectivity of the reflective film decreases as a thickness thereof decreases, and a light transmittance of the reflective film increases as a thickness thereof decreases; and wherein a thickness of a portion of the reflective film located in the first region is larger than a thickness of a portion of the reflective film located in the second region.
