  • Patent number: 7990051
    Abstract: An organic light emitting device includes a display panel, and a polarizer that is positioned on the display panel and includes a retarder and a polarizing film. The polarizing film includes a base layer and shielding patterns positioned inside the base layer. An area of the shielding pattern close to the display panel is larger than an area of the shielding pattern far away from the display panel. The shielding pattern is formed in a non-emitting area of the display panel.
