摘要： A high-speed flat panel display having a long lifetime. Thin film transistors in a pixel portion having a plurality of pixels are contacted differently from thin film transistors in driving circuit portions for driving the pixels, thereby enhancing luminance uniformity and reducing power consumption. The thin film transistors each have a channel region and a body contact region for applying a predetermined voltage to the channel region. At least one thin film transistor in the pixel portion is a source-body contact thin film transistor having the body contact region connected to one of source and drain electrodes so that the predetermined voltage can be provided to the channel region. Each thin film transistor in the driving circuit portion is a gate-body contact thin film transistor having the body contact region connected to the gate electrode so that a predetermined voltage can be provided to the channel region.

摘要： An organic light emitting diode (OLED) is capable of improving light efficiency per pixel unit by forming a cathode electrode to cover an anode electrode, thereby focusing light emitted from a luminescent layer per pixel unit. The OLED comprises: a second insulating film formed on a substrate including a TFT with source/drain electrodes formed on a first insulating film; a lower electrode formed on the second insulating film and connected to one of the source/drain electrodes; a third insulating film having an opening for exposing a portion of the lower electrode; a luminescent layer formed on the lower electrode inside the opening; a groove formed to surround the luminescent layer; and an upper electrode formed on the substrate including the groove so that the upper electrode surrounds the luminescent layer. The upper electrode functions as a reflection layer for reflecting total light while light emitted from the luminescent layer is being pulled out through the substrate.

摘要： The invention provides an active matrix organic light emitting display device and method of fabricating the same in which at least one of a data line and a power supply line of a unit pixel is designed to pass over at least one of a source region, a channel region, or a drain region in the corresponding semiconductor layer, except for in an area corresponding to a contact hole, so that an aperture ratio and a pixel size of the active matrix organic light emitting display device are enhanced. This arrangement of components creates areas of free space that may be used to accommodate additional thin film transistors and/or other circuit components that improve the screen resolution. This arrangement may also increase the aperture ratio and the size of the pixel of the active matrix organic light emitting display device without adding and modifying existing fabrication processes.
