, TW4973PA filter substrate 108. The thin film transistor matrix structure 16 includes a transparent substrate 120, a plurality of halogen electrodes 118, and a plurality of signal lines 11〇(1), 11〇(2) and 110(3), for example, a data line (Data line) ). As shown in FIG. 2, the color filter substrate 1 〇 8 is disposed adjacent to the thin film transistor matrix structure 106 and includes a transparent substrate 112 and a plurality of first filter structures 114 (1), 114 (2), 114 (3). ) and 114 (4). The position of the first filter structure may correspond to the halogen electrode 118. Wherein the adjacent ones of the first filter structures 114(1), 114(2), 114(3) and 114(4) are connected to each other' and the first filter structure is between the two Corresponds to the location of the signal line. For example, the portion 122 between the red filter structure 114(1) and the blue filter structure 114(3) corresponds to the position of the signal line 11〇(1) 'red filter structure 114(1) and green filter The portion 124 between the light structures 114(2) corresponds to the position of the signal line, and the portion 126 between the green filter structure 114(2) and the blue filter structure 丨丨4(3) corresponds to the signal line 110 (2) )s position. φ As shown in Fig. 2, the light-transmitting substrate 112 has a substrate surface 116 facing the thin germanium crystal matrix structure 1〇6. The first light-emitting structures 114(1), 114(2), 114(3) and 114(4) are formed on the substrate surface 116'. The first filter structures ιΐ4(ι), ii4(2), 14( 3) and 114(4) can filter out a predetermined light color. For example, the red filter structure 114(ι) is used to allow the light L1 to pass red afterwards, and the green filter structure 114(2) to allow the light L1 to be green after passing through the blue filter structure 114(3) Used to make the light L1 blue after passing. In particular, a blue filter structure 114 ( 4 ) is disposed between the adjacent red filter structure 114 ( 1 ) and the green filter structure 114 ( 2 ) to replace the conventional black matrix, that is, The color filter substrate 108 of the embodiment 201120489 does not have a black matrix. Since the color filter substrate of the present embodiment replaces the conventional black matrix with the blue filter structure 114(4) at the portions corresponding to the signal lines 110(1), 110(2) and 110(3). Therefore, the light color of the light L2 passing through the portions 122, 124, and 126 is a second light color, that is, blue. The display panel 104 of the present embodiment is exemplified by a transmissive display panel. However, the display panel of the other embodiments may not be limited to the embodiment.

In the embodiment in which the transflective display panel is used, the backlight from the portion of the backlight module 1〇2 is covered by the reflective electrode (not shown) of the reflective region on the thin film transistor matrix structure. Therefore, only a small amount of backlight reaches the portions 122, 124, and 126 of the color filter substrate 1 to correspond to the signal lines. The color filter structure in place of the black matrix in this embodiment is sufficient to shield such a small amount of backlight, in which case the light 12 having the second light color has a limited display quality, and does not affect the display quality. The first filter structure 114 ( 4 ) corresponding to the signal lines 110 ( 1 ), 110 ( 2 ), and 110 ( 3 ) in the color filter substrate 108 of the present embodiment is exemplified by a blue filter structure. However, the first filter structure 114 (4) may also be a red filter structure, a green filter structure or other light color filter structures, and is not limited by the present embodiment. Further, please refer to Fig. 3 (the first filter structure is not shown), which is a schematic view of the color filter substrate viewed in the direction VI of Fig. 2. In order to avoid over-complicating the illustration, the first filter structures 114(1), 114(2), 114(3) and 114(4) are not shown in FIG. 201120489

The color-lighting substrate of this alternative embodiment! 3 4 includes a third filter structure 132' such as a blue filter structure. The third filter structure 132 is disposed on an edge region of the transparent substrate 112 to replace the conventional black matrix. Although the third filter structure 132 has a non-black matrix, it still has the effect of shielding the light leakage and preventing the light leakage from affecting the display quality. Also, the edge region of the light-transmitting substrate 112 is not a display region. Therefore, if light is emitted from the & edge region, the display quality of the display device 100 is limited, and the display quality is not affected. θ In addition, although the third filter structure 132 of the present embodiment is exemplified by a blue filter structure, it may be a red filter structure, a green filter structure, or a light-emitting structure of other light colors.

Such a large savings in process time and cost can save the mask cost and process time required for the fabrication of conventional black matrices and conventional metal alignment marks. The second embodiment «月> ... Fig. 5 is a schematic view showing a color + color filter substrate according to a second embodiment of the present invention. The color filter substrate of the second embodiment is different from the color light-emitting substrate (10) of the first embodiment in that the color filter substrate 2G8 corresponds to the signal lines UG(1), 11G(2) and 110(3) (shown in The part of Fig. 2) may have no structure. For example, there is a gap between the red fluorescent structure 114(1) and the green filter, light structure 114(2) - the distance D, that is, the gap between the 'red filter structure 114(1) and the green filter structure 114(2). * The distance between the green filter structure 114(2) and the blue filter structure 114(3) is D1, that is, the green filter structure 114(2) and the blue filter, >. There is a gap between the structures 114(3). The same reference numerals are used throughout the rest, and will not be described here. The portion of the color filter substrate 208 of the present embodiment corresponding to the signal lines 110(1), 110(2), and 11〇(3) (shown in FIG. 2) does not have any structure, for example, does not have a black matrix and Color filter structure.
