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.
