Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The color membrane substrates provided the embodiment of the present invention below in conjunction with accompanying drawing and display panels are described in detail.
Embodiments provide a kind of display panels, as shown in Figure 1, this display panels comprise color membrane substrates 10, the array base palte 20 that arranges with described color membrane substrates 10 pairs of boxes and the liquid crystal 30 being arranged on described color membrane substrates 10 and described array base palte 20 centre.
Wherein, the described color membrane substrates 10 color rete 103 that comprises substrate 101, be arranged on the polaroid 102 on described substrate 101 1 surface and be arranged on described another surface of substrate 101.Described color rete 103 comprises red, green, blue sub-pixel (being shown as 1031,1032,1033 successively in figure), also can be provided with black matrix 1034, also according to general knowledge known in this field or common technology means, black matrix 1034 can be arranged on other layers of color membrane substrates 10.Described array base palte 20 is provided with thin film transistor (TFT) 201.Black matrix 1034 is arranged on the position relative with thin film transistor (TFT) 201.
As shown in Figure 1, described color rete 103 is also provided with photoprotection layer 104.Described photoprotection layer 104 is a kind of optical element, and can reduce the light be reflected back by color membrane substrates 10 injecting the light of color membrane substrates 10 via described photoprotection layer 104, described light is mainly ultraviolet light and blue light.
Wherein, under the duty of display panels, backlight emits beam 1, injects array base palte 20, liquid crystal 30 and color membrane substrates 10 successively.The light 1 that backlight sends is injected in color membrane substrates 10 via described photoprotection layer 104, and light is while incidence, and can reflect at the element place such as polaroid 102, color rete 103 in color membrane substrates 10, reflection ray 3 can be penetrated back towards array base palte 20.Photoprotection layer 104 can reduce the light 3 be reflected back by color membrane substrates 10.The light of this minimizing mainly makes thin film transistor (TFT) 201 produce the ultraviolet light and blue light etc. of photocurrent.Because black matrix 1034 and thin film transistor (TFT) 201 are oppositely arranged in position, therefore photoprotection layer 104 especially can reduce the ultraviolet light or blue light that black matrix 1034 reflects towards thin film transistor (TFT) 201.Compared with the structure of the display panels of the prior art shown in Fig. 2, the photoprotection layer 104 in the embodiment of the present invention can reduce major part is reflected back array base palte 20 light 3 from color membrane substrates 10, especially ultraviolet light and blue light.
