Abstract: Light emitted within an organic EL device is effectively utilized, and a pixel is provided for improving the extraction efficiency of the light. Light extraction is efficiency is improved without increasing a current by effectively utilizing guided wave light which is a cause of the loss of light emitted by an organic EL device. In order to achieve this, a stepped portion is arrange in an insulating layer provided over a lower layer of a first electrode including a light reflecting surface, and a peripheral area of the first electrode is formed so as to contact the stepped portion. The reflecting surface is formed curved towards a second electrode side in the peripheral area of the first electrode from the stepped portion, light guided through the organic EL layer is reflected by the reflecting surface and emitted from the second electrode side.

Abstract: The adjustment of a color temperature is made possible in a display panel using a white light-emitting OLED. The white light-emitting OLED includes a light-emitting layer containing light-emitting materials of respective colors of R, G, and B. By changing the current density of a drive current to be supplied to the white light-emitting OLED, light emission of the OLED is adjusted to a color temperature in response to an instruction from a user. A period PD in which the OLED emits light is changed in inverse proportion to a change in drive current so as to maintain emission luminance in one frame for the emission intensity of the OLED changing in response to the drive current.
