摘要： The gate electrode is formed above the polycrystalline semiconductor layer through the gate insulating film. The polycrystalline semiconductor layer includes a first region overlapping with the gate electrode in plan view. The first region is sandwiched between the second region and the third region. The second region of the polycrystalline semiconductor layer includes a first impurity diffusion region and two second impurity diffusion regions opposite in conductivity type to the first impurity diffusion region. The first region and the first impurity diffusion region are in contact with each other at a first boundary. The first region and the two second impurity diffusion regions are in contact with each other at second boundaries. The two second impurity diffusion regions sandwiching the first impurity diffusion region are provided along the gate electrode. Thus, a leak current is suppressed.

摘要： The present invention provides a display-device-use substrate which is strip-crystallized while minimizing the generation of peeling of a semiconductor by suppressing the generation of aggregation at the time of crystallization due to the radiation of continuous oscillation laser beams. A silicon nitride film and a silicon oxide film which constitutes a background film are formed on a glass substrate on which projecting portions are formed, and a silicon base film is formed on the silicon nitride film and a silicon oxide film. Banks which intersect the scanning directions of laser beams are positioned below the silicon base substrate. The aggregation which is generated by the scanning of laser beams is stopped at a portion after the laser beams gets over the bank and, thereafter, the strip crystal silicon film is formed normally.

摘要： A liquid crystal display device includes a first substrate and a second substrate with a liquid crystal layer therebetween. The first substrate includes drain lines, gate lines, thin-film transistors that output signals to pixel electrodes, and an organic film that is formed between each thin-film transistor and each pixel electrode. The organic film has a contact hole for electrical connection between a source electrode of each thin-film transistor and each pixel electrode. A step is formed in a layer underlying the organic film and an edge portion of the organic film toward the thin-film transistor, the edge portion forming the contact hole, being formed to lie on a lower plane of the step. A sidewall part of the contact hole which is formed in the organic film is formed to have a taper angle of at least 60 degrees.

摘要： A cut which penetrates a resin layer is formed in the resin layer such that the cut surrounds a third upper surface. A film is formed such that the film covers the whole resin layer except for a bottom surface of the resin layer inside the cut and at least a portion of the resin layer is exposed outside the cut. The resin layer which is wholly covered with the film is left inside the cut, and the whole resin layer continuously formed with a surface exposed from the film is removed outside the cut. A bump is formed by the resin layer and the film inside the cut, and a shutter and at least a portion of a drive part are formed by the film outside the cut in a state where these parts are floated from a first substrate.
