Abstract: PROBLEM TO BE SOLVED: To provide an organic electroluminescent element for simultaneously connecting power supply wiring to an adjacent pixel. SOLUTION: In this organic electroluminescent element for improving particularly an opening rate and a method for manufacturing the element, the organic electroluminescent element is formed so that the positions of drive elements formed in the pixels adjacent to each other are positioned close to each other to simultaneously receive signals with one power supply line. Thus, since the number of the power supply lines can be halved as compared with conventional elements, defective wiring can be prevented by improving the opening rate and brightness of the organic electroluminescent element.

Abstract: PROBLEM TO BE SOLVED: To design shapes of a gate electrode and a drain electrode into a new structure, to miniaturize parasitic capacity CGD between the drain electrode and the gate electrode and to provide a liquid crystal panel of high picture quality. SOLUTION: A liquid crystal display device, especially, a switching element deciding an operation characteristic of the liquid crystal display device are provided. In the switching element constituted of the gate electrode, an active layer, a source electrode and the drain electrode, one side of a part which is overlapped with the drain electrode in one side of the gate electrode is constituted in a shape bent inside. Since a parasitic capacitance value C gs generated while the drain electrode is overlapped with the gate electrode becomes small, flicker does not occur. Consequently, the liquid crystal display device of high picture quality can be manufactured. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To prevent a test wire from being broken during dry etching and to prevent a test error by shortening a process time by forming source and drain electrodes of molybdenum and forming the test wire of a gate substance. SOLUTION: When a short bar which is formed on the outer shell of a substrate and can connect an odd-numbered gate wire and an even-numbered data wire and a test pad applying a signal for inspection to the short bar are connected through a connecting wire in a 4-mask process using molybdenum as substances forming the source and drain electrodes, the formation of the connection part of molybdenum can be avoided by forming each test pad and the connecting wire of the gate substance and indirectly connecting the connection part to the short bar formed of molybdenum (Mo) by using a different transparent electrode pattern, so the defect that the connecting wire formed on the outer shell of the substrate is etched can be prevented during a process of patterning the source electrode and drain electrode.
