摘要： According to one embodiment, a method of manufacturing an organic EL device is disclosed. The method can arrange an adhesive agent of an ultraviolet curable type between a first substrate on which a plurality of light emitting parts are formed in a predetermined direction and a second substrate arranged to face the first substrate separately so as to surround the light emitting parts. Each of the light emitting parts comprises a plurality of organic EL elements. The method can form a substrate pair by exposing the adhesive agent to ultraviolet rays to bond the first substrate and the second substrate to each other with the adhesive agent. The method can place the substrate pair on a first holding member capable of holding an entire surface of the first substrate or the second substrate. The method can place the substrate pair on a second holding member after a predetermined period of time has passed, the second holding member being capable of holding the substrate pair with at least two supporting members positioned along the first substrate or the second substrate. The method can cut the substrate pair around the adhesive agent with each of the light emitting parts as a unit.

摘要： A plurality of pixel units are arranged in a matrix, each pixel unit including a display element and a pixel circuit which supplies a driving current to the display element. Each pixel circuit includes a first memory section which stores, in a write period of the pixel unit, a first driving current corresponding to a first signal current and then outputs the stored first driving current, and further stores a second driving current corresponding to a second signal current, and a second memory section which stores the first driving current output from the first memory section in the write period of the pixel unit. The pixel circuit outputs, in a light emission period of the pixel unit, a difference current between the second driving current stored in the first memory section and the first driving current stored in the second memory section to the display element as the driving current.
