More preferably, the full-width d2 of the half-peak of the second green filter pattern G2 is, for example, less than 90 nm. Thus, the second green filter can be made. The wavelength 318b of the transmission wavelength of the pattern G2 and the first and second peaks 326a, 326b of the light emission spectrum 326 of the light source 324 cooperate to filter out the second green light. According to the above, since the first and second green filter patterns G1 and G2 can respectively filter, the first and second green lights, and the red light filtered by the red light pattern r and the blue filter pattern B, In the present embodiment, the color filter pattern 318 can filter out the four primary colors, and the color saturation of the liquid crystal display can be improved by the full color image displayed by the four primary colors. Figure 7 is a chromaticity diagram of the International Illumination Commission 1931 (CIE 1931) standard chromaticity system. Please also refer to Figure 5 and Figure 7. One of the ways to calculate the color saturation 251·_06 and degree is compared with the standard value set by the National Television System Committee (ntsc), and the National Television System Committee. The area of the triangle formed by connecting the three coordinate points r, g, and b in FIG. 7 is set to a color saturation of 100%. In the present embodiment, the liquid crystal display 3 has four primary colors 'which are coordinate points ri in FIG. 7 (〇.676, 〇, gl (0.149, 0.593), g2 (0.254, 0.694), b (0.142, 0.076). ) Four coordinate points. Since the area formed by the connection of the four punctuation points rl, gl, g2, and b is larger than the area formed by the line connecting the coordinate points r, g, and b, the liquid crystal display of the present embodiment 300 The color saturation is greater than the 100% standard of the National Television and Television Association, and even more than 112%. _ Figure 8 is a cross-sectional view showing another structure of the liquid crystal display of the present invention. This embodiment is similar to the liquid crystal display of FIG. 5, except that the color filter pattern 318 is disposed on the lower substrate 312, that is, the color filter pattern 318 is disposed on the same substrate as the thin film transistor array (not shown). In addition, it is also called a color filter on array (COA) on the array. Of course, the design of the color filter pattern with four primary colors of the present invention can also be applied to other kinds of liquid crystal displays. , for example, multi-domain vertical alignment type ( Multi-d〇main Vertically φ Alignment mode, MVA mode), In-plane switching mode (IPS mode). It is worth mentioning that, in any of the above liquid crystal displays, the color filter pattern 318 The arrangement may be a strip arrangement (as shown in FIG. 4A) or a four-pixel mosaic arrangement (as shown in FIG. 4B). In summary, the color filter substrate of the present invention adopts a first green filter pattern. And replacing the first green light pattern with the second green calender pattern by replacing the conventional green-green light map 13 f.doc/006 and selecting the first green filter pattern having the appropriate penetration wavelength Filtering out more layers of green light (green light of more wavelengths), so the color filter substrate of the present invention can extract the four primary colors, and the full color image can be displayed by the four primary colors to improve the liquid crystal. The color saturation of the display. In addition, the liquid crystal display of the present invention replaces the conventional single green filter pattern by using the first-green light, and the second green filter pattern, and selects the appropriate penetration wavelength. of A green filter pattern and a second f-color filter 11 are matched with the peaks of the light-emitting luminescence spectrum of the backlight module in the green light circumstance, so that more layers of green light can be filtered out (more The green light of a plurality of wavelengths, so the color f in the liquid crystal display of the present invention can filter out the four primary colors. By the combination of the four primary colors, the color saturation of the liquid crystal display is greater than that of the US country = 糸, 4 The standard of 1W6 set by the detailed meeting may even reach 112%.
