| 发明名称 | Organic light emitting diode display | ||
| 摘要 | An organic light emitting diode display has uniform light emission efficiency over the entire pixel area. The organic light emitting diode display comprises: a substrate having a red pixel area, a green pixel area, and a blue pixel area arrayed in a matrix; an anode electrode in the red, green, and blue pixel areas; a hole injection layer including an organic material with an extinction coefficient less than about 0.13 and on the anode electrode covering a whole surface of the substrate; an emission layer on the hole injection layer; an electron injection layer on a whole surface of the emission layer; and a cathode electrode on a whole surface of the electron injection layer. | ||

| 主权项 | 1. An organic light emitting diode display comprising: a substrate having a red pixel area, a green pixel area, and a blue pixel area arrayed in a matrix; an anode electrode in the red, the green, and the blue pixel areas; a hole injection layer on the anode electrode including an organic material with an extinction coefficient from about 0.05 to about 0.13 and covering a whole surface of the substrate; an emission layer on the hole injection layer; an electron injection layer on a whole surface of the emission layer; and a cathode electrode on a whole surface of the electron injection layer. | ||
