Colored optical filtering substrates 100 of the present invention can be adopted to make display panels and liquid crystal display.Fig. 4 a is the broken section structural representation of display panels of the present invention.As shown in fig. 4 a, in the present embodiment, display panels 10 comprises colored optical filtering substrates 100, liquid crystal layer 200 and array base palte 300, liquid crystal layer 200 is arranged between array base palte 300 and colored optical filtering substrates 100, and the photochromatic layer 150 of colored optical filtering substrates 100 is positioned at the side near liquid crystal layer 200.
Fig. 4 b is the schematic diagram that display panels of the present invention carries out monochromatic luminescence display.As shown in Figure 4 b, when the liquid crystal display being provided with display panels 10 of the present invention carry out monochrome light display (such as only carry out green (G) look color blocking and light display) time, the liquid crystal molecule 201 be positioned at below green (G) look color blocking deflects under the effect being subject to electric field force, the light sent in order to make backlight module can through the liquid crystal layer 200 in this region, and directive colored optical filtering substrates 100 (liquid crystal molecule 201 be not subject in the region of electric field force effect does not deflect, that is, this region liquid crystal layer 200 shows as light tight); When the light vertical incidence that backlight module sends is to colored optical filtering substrates 100, light can normally through the region of green (G) look color blocking of the photic zone 152 of photochromatic layer 150 and color blocking layer 130; When the light oblique incidence that backlight module sends is to colored optical filtering substrates 100, light is absorbed after the light shield layer 154 of photochromatic layer 150, light is prevented to enter other regions except green (G) look color blocking, (light shows green through during green (G) look color blocking to effectively reduce the colour mixture occurred when display panels 10 carries out monochromatic display, light shows as blueness through during blue (B) look color blocking, just there will be colour mixture when green and blueness show simultaneously) problem.
What the black matrix layer 120 of colored optical filtering substrates 100 of the present invention and color blocking layer 130 were spaced is arranged on substrate 110, transparency conducting layer 140 to be arranged on substrate 110 and to cover black matrix layer 120 and color blocking layer 130, photochromatic layer 150 is arranged on transparency conducting layer 140, photic zone 152 and the spaced setting of light shield layer 154 of photochromatic layer 150, and light shield layer 154 is positioned at the top of black matrix layer 120.When the liquid crystal display being provided with colored optical filtering substrates 100 of the present invention carry out monochrome (such as carrying out green (G) look) light display time, oblique incidence is absorbed after the light shield layer 154 of photochromatic layer 150 to the light of colored optical filtering substrates 100, prevent light to enter other regions except green (G) look color blocking, the colour mixture problem occurred when liquid crystal display carries out monochromatic display can be effectively reduced.And the light shield layer 154 of photochromatic layer 150 can effectively block the reflective of the metal level of array base palte 300, can reduce the light leakage phenomena of liquid crystal display.
Below the preferred embodiment of the present invention is described in detail by reference to the accompanying drawings; but the present invention is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present invention; can carry out multiple simple variant to technical scheme of the present invention, these simple variant all belong to protection scope of the present invention.Each concrete technical characteristic described in above-mentioned embodiment, in reconcilable situation, can be combined by any suitable mode.In order to avoid unnecessary repetition, the present invention illustrates no longer separately to various possible array mode.
