Abstract: A thin-film transistor is formed by a polycrystalline silicon film having a thin-film part and a thick-film part, the thin-film part minimally being used as a channel part. The polycrystalline silicon film is formed by laser annealing with an energy density that completely melts the thin-film part but does not completely melt the thick-film part. Because large coarse crystal grains growing from the boundary between the thin-film part and the thick-film part form the channel part, it is possible to use a conventional laser annealing apparatus to easily achieve high carrier mobility and low leakage current and the like.

Abstract: A liquid-crystal display device makes it possible to attach an optical element to a liquid-crystal display panel with high positional accuracy while avoiding or minimizing the enlargement of the picture-frame region (i.e., the non-display region) induced by the formation of markers on the panel and the increase of the fabrication cost. The panel comprises a main substrate, an opposite substrate, and a liquid crystal enclosed in a gap between the main and opposite substrates, wherein a polarizer plate is attached at least to the opposite substrate. Markers for attaching an optical element to the panel are formed at positions that overlap with the polarizer plate in a non-display region on the main or opposite substrate. Alignment direction regulators regulate the alignment of the liquid crystal molecules to a predetermined direction in the vicinities of the markers, allowing light to pass through at least the opposite substrate.

Abstract: The TFT substrate of an LCD device has an array of pixel electrodes defined by a plurality of signal lines and a plurality of scanning lines. Each terminal of the scanning lines includes a first metallic pattern, a second metallic pattern in contact with the first metallic pattern through a first via hole, and an ITO pattern in contact with the second metallic pattern through a second via hole. The ITO pattern has a width smaller than the width of the first via hole and larger than the second via hole, thereby providing the TFT substrate with a smaller level difference. The smaller level difference prevents the dust generated during a rubbing treatment from attaching onto the TFT substrate.

Abstract: In a liquid crystal display apparatus, a set of write-in voltages are generated corresponding to a horizontal line signal of an input video frame so that they appear at end points of the column lines of a LCD panel. The row lines of the LCD panel are successively selected and the write-in voltages are supplied from the end points of the column lines to the liquid crystal cells of the selected row line for a variable write-in period. In order to compensate for shades-of-gray differences between the top and bottom of the LCD panel, the write-in period is increasingly varied as a function of the geometric distance from the selected row line to the end points of the column lines. The write-in period may be increasingly variable from a nominal value, or from a less-than-nominal value to the nominal value, or a combination of both.

Abstract: A TFT (Thin Film Transistor) is provided in which a hydrogen feeding layer is able to be formed in a position where diffusing distance of hydrogen can be made short without causing an increase in photolithography processes. In the TFT, the hydrogen feeding layer to diffuse hydrogen into a dangling bond existing at an interface between a polycrystalline silicon thin film and a gate insulating film is formed in a position between the gate insulating film and a gate electrode. According to this configuration, diffusing distance of hydrogen at a period of time during hydrogenation can be made short and the hydrogenation process can be sufficiently performed without taking time in heat treatment.
