The part feux rouges and blue light of receipts are converted to green light, so that the light of the feux rouges of non-bent area C, blue light and green light is matched and is expected
Three kinds of colors of red blue green light proportion it is identical；For bent area B, the chromophoric group of the biggish organic dyestuff of concentration can be inhaled
More blue lights and part feux rouges are received, and the blue light of absorption and feux rouges can be converted to green light, is shown with to improve bent area B and is turned blue
The phenomenon that, and the feux rouges of bent area B, the light proportion of blue light and green light and the light of expected three kinds of colors of RGB are matched
Than identical, in this way, by the concentration of the chromophoric group of the organic dyestuff in the first optical adjustment layer 71 and the second optical adjustment layer 72
Different doping are carried out, can targetedly reduce the colour cast of the bent area B and non-bent area C of display panel 100, while can also
Improve bent area B and show the phenomenon that turning blue, is equally beneficial for improving the whole display effect of display panel 100.
Based on the same inventive concept, the application also provides a kind of display device, and Fig. 8 show display provided herein
