[0068] FIG. 3A is a schematic cross-sectional view of the color filter substrate according to the first embodiment of the present invention. Referring to FIG. 3A , the color filter substrate 300 includes a substrate 310 , a black matrix layer 320 , a first filter layer 330 and a second filter layer 340 . The black matrix layer 320 is disposed on the substrate 310, and the black matrix layer 320 divides a plurality of pixel regions 350 on the substrate 310, wherein each pixel region 350 includes a first sub-pixel region 352 and a second sub-pixel region 354 . Both the first filter layer 330 and the second filter layer 340 are disposed in the pixel region 350, and the second filter layer 340 covers the first filter layer 330, wherein the second filter layer 340 has a higher refractive index than the first filter layer. The refractive index of the filter layer 330 is such that the light emitting direction of the first sub-pixel area 352 is different from the light emitting direc...

[0077] FIG. 4 is a schematic cross-sectional view of a color filter substrate according to a second embodiment of the present invention. Referring to FIG. 4 , the color filter substrate 302 is similar to the color filter substrate 300 of the above-mentioned embodiment, and only the differences are described here.
[0078] In this embodiment, the first filter layer 330 is, for example, a color filter layer, that is, the first filter layer 330 may be composed of a red filter layer 330R, a green filter layer 330G, and a blue filter layer 330B. . Of course, the present invention does not limit the color combination and arrangement of the first filter layer 330 . In addition, the second filter layer 340 is, for example, a transparent color layer, and in particular, the cross-sectional shape of the second filter layer 340 is a triangle. In this way, the principle of total reflection can be used to make the light emitting direction of the first sub-pixel area 352 different from the...

[0081] FIG. 5 is a schematic cross-sectional view of a color filter substrate according to a third embodiment of the present invention. Referring to FIG. 5 , the color filter substrate 304 is similar to the color filter substrates 300 and 302 of the above-mentioned embodiments, and only the differences are described here.
[0082] In this embodiment, the substrate 310 further includes a plurality of grooves 312 with a triangular cross section, and the first filter layer 330 , the second filter layer 340 and the black matrix layer 320 are disposed in each groove 312 .
[0083] Likewise, in this embodiment, the first filter layer 330 is, for example, a transparent color layer, especially, the first filter layer 330 is filled into the groove 312 whose cross-sectional shape is triangular. After the first filter layer 330 is formed, the second filter layer 340 is continuously fabricated. The second filter layer 340 is, for example, a color filter layer, and may be composed of a re...
