The utility model content
First technical matters to be solved in the utility model is, a kind of homogeneity that can avoid influencing the LCD liquid crystal layer is proposed, make the thick uniform colored filter of colour liquid crystal display device box, solve R-G-B dyed layer and the inaccurate problem of ITO cabling contraposition that external colored filter exists simultaneously when being used for LCD.
The technical matters that the utility model further will solve is, a kind of colour liquid crystal display device that adopts described colored filter to make is proposed, on the basis that does not increase cost, solve the box thickness ununiformity problem of the LCD existence of using conventional colored filter, R-G-B dyed layer and the inaccurate problem of ITO cabling contraposition that solution simultaneously uses the LCD of external colored filter to exist.
For colored filter of the present utility model, its technical matters is solved by following technical scheme:
This colored filter comprises the printing opacity substrate, and the one side of this printing opacity substrate is provided with BM successively superimposedly, has the dyed layer that shows R-G-B three primary colors zone respectively of light transmission, OC layer.
The characteristics of this colored filter are:
The another side of printing opacity substrate is provided with the ITO conductive layer.
For the colour liquid crystal display device that the described colored filter of employing of the present utility model is made, its technical matters is solved by following technical scheme:
This colour liquid crystal display device comprises superimposed successively oriented layer, colored filter, polaroid.
The characteristics of this colour liquid crystal display device are:
The ITO conductive layer and the oriented layer of described colored filter are superimposed, and the OC layer and the polaroid of colored filter are superimposed.
For the colour liquid crystal display device that the described colored filter of employing of the present utility model is made, its technical matters is solved by following further technical scheme:
This colour liquid crystal display device comprises also that from the superimposed successively liquid crystal layer of described oriented layer another side, following oriented layer, sputter the printing opacity substrate of ITO conductive layer, following polaroid are arranged.
Also comprise module backlight, described polaroid another side down and described module backlight are fitted.
This colour liquid crystal display device comprises also that from the superimposed successively liquid crystal layer of described oriented layer another side, last oriented layer, sputter the printing opacity substrate of ITO conductive layer, last polaroid are arranged.
Also comprise module backlight, described polaroid another side and described module backlight are fitted.
The beneficial effect that the utility model is compared with the prior art is:
The dyed layer in black matrix" light shield layer, R-G-B three primary colors zone and protective seam are positioned at a side of printing opacity substrate; the ITO conductive layer is positioned at the opposite side of printing opacity substrate; the flatness of ITO conductive layer can not be subjected to the influence of the dyed layer in black matrix" light shield layer, R-G-B three primary colors zone; with respect to conventional colored filter; flatness can obviously promote; the thick homogeneity of box of improving colour liquid crystal display device is very helpful, on the basis that does not increase cost, has solved the box thickness ununiformity problem of the LCD existence of using conventional colored filter.
The used colored filter of the utility model is directly used in the manufacturing process of LCD, use directly exposure formation ITO cabling on colored filter of chromium plate, exist the ITO cabling of the R-G-B dyed layer of colored filter and LCD to be difficult to the problem of accurate contraposition when having avoided known technology to use external colored filter, realized the accurate contraposition between the ITO cabling.Simultaneously, do not increase new production process and material yet, can not increase cost.
