  • Patent number: 8816349
    Abstract: By using a conductive layer including Cu as a long lead wiring, increase in wiring resistance is suppressed. Further, the conductive layer including Cu is provided in such a manner that it does not overlap with the oxide semiconductor layer in which a channel region of a TFT is formed, and is surrounded by insulating layers including silicon nitride, whereby diffusion of Cu can be prevented; thus, a highly reliable semiconductor device can be manufactured. Specifically, a display device which is one embodiment of a semiconductor device can have high display quality and operate stably even when the size or definition thereof is increased.

  • Patent number: 8643270
    Abstract: When a light-emitting element having an intermediate conductive layer between a plurality of light-emitting layers is formed, the intermediate conductive layer can have transparency; and thus, materials are largely limited and the manufacturing process of an element becomes complicated by a conventional method. A light-emitting element according to the present invention is formed by sequentially stacking a pixel electrode, a first light-emitting layer, an intermediate conductive layer (including an electron injecting layer and a hole-injecting layer, one of which is island-like), a second light-emitting layer and an opposite electrode.

    Abstract: An image forming apparatus includes a sheet feeding device that corrects skew of a sheet before feeding the sheet to a transfer position for image formation. The sheet feeding device comprises a driver, a feeder roller unit provided with a feeder roller rotationally driven by the driver and a separation roller, and two resist roller units each provided with a primary and a secondary resist roller. The resist roller units cause formation of a loop in the sheet between the resist roller units and the feeder roller unit during skew correction. When viewed in a direction of a rotational axis of the feeder roller, the first resist rollers and the feeder roller overlap at least partially, and the pressing member and the second resist rollers do not overlap. The first resist rollers and the feeder roller occupy different positions with respect to the direction of the rotational axis.

  • Patent number: 8492968
    Abstract: A sealing structure is provided without irradiating a pixel portion of a light emitting element by heat or UV light. By the sealing structure, the reliability is enhanced by blocking out oxygen and moisture, and preventing the deterioration of the light emitting element. The sealing structure in which a whole surface of the pixel portion is covered with a sealing material and which has an excellent sealing property is manufactured without being exposed to heat or UV light. In this case, a catalyst for curing a sealing material is formed as a film on a substrate, and a sealing material for covering a pixel portion is applied to the other substrate. Then, the both substrates are bonded together.
