摘要： In an organic EL display device, a resistance of a cathode electrode of OLEDs is substantially reduced while maintaining a higher opening ratio of pixels as an entire display area. A reference power supply line is formed on a glass substrate, and receives a reference potential for driving the OLED. The OLED is formed on the glass substrate where the reference power supply line is formed, and has a structure in which a lower electrode, an organic material layer, and an upper electrode that is a cathode electrode common to plural pixels are laminated on each other in the order from the bottom. In some of the plural pixels, a cathode contact that penetrates through the organic material layer, and electrically connects the upper electrode to the reference power supply line is formed within an opening area corresponding to a W sub-pixel.

摘要： An organic EL display device includes: a lower electrode; an upper electrode; a first organic layer which is disposed between the lower electrode and the upper electrode and is formed of a plurality of layers including a light emitting layer formed of an organic material that emits light; a metal wire that extends between the pixels within the display region; and a second organic layer which is formed of a plurality of layers the same as that of the first organic layer and which comes into contact with a part of the metal wire and does not come into contact with the first organic layer. The upper electrode comes into contact with the metal wire in the periphery of the second organic layer.

摘要： A display device, in which self-luminous elements are arranged, prevents a leakage current through a common layer, provided for the self-luminous elements and disposed throughout its image display area, from causing adjacent pixels to emit unintended light. A light-emitting element layer 102 includes a lower layer 102d and a light-emitting layer. The lower layer 102d has carrier mobility and includes a carrier transport layer or a carrier injection layer. The lower layer 102d is stacked on lower electrodes 100 and banks 106. The light-emitting layer is stacked on the lower layer 102d. An upper electrode 62 is disposed on the light-emitting element layer 102 and supplies carriers to the light-emitting element layer 102 together with each lower electrode. A lower layer 102d has a dividing area 112 on the bank. The dividing area 112 prevents carriers from traveling between adjacent pixels through the lower layer 102d.
