20160377917 | LIQUID CRYSTAL PANEL AND THE MANUFACTURING METHOD THEREOF - A display panel and the manufacturing method thereof are disclosed. The display panel includes a top substrate, a down substrate, a photoresist layer between the top substrate and the down substrate. The display panel includes a transmission area and a reflective area having a reflective layer within the photoresist layer. The reflective layer divides the photoresist layer into a first sub-photoresist layer and a second sub-photoresist layer. The first sub-photoresist layer is arranged between the reflective layer and the down substrate. The second sub-photoresist layer is arranged between the reflective layer and the top substrate. The light beams within the transmission area pass through the photoresist layer, the light beams within the reflective area pass through the first sub-photoresist layer or the second sub-photoresist layer twice. In this way, the saturation of the transmission area and the reflective area are compatible. | 12-29-2016 |
