20120182491 | LIQUID CRYSTAL DISPLAY DEVICE - The present invention provides a liquid crystal display device that uniformly stabilizes the alignment direction of liquid crystal molecules, prevents display roughness and what is called an afterimage phenomenon in which a previous display state remains unchanged in switching display, has excellent display performance, and responds to finer pixels. A liquid crystal display device of the present invention comprises: a pair of substrates; and a liquid crystal layer sealed between the pair of substrates, wherein the liquid crystal layer contains liquid crystal molecules that are aligned vertically to a substrate surface when no voltage is applied, at least one of the pair of substrates includes a pixel electrode, a gate bus line, and a source bus line, the pixel electrode is provided with a slit, the slit bends, and a part of the slit is along the gate bus line. | 07-19-2012 |
20120281171 | LIQUID CRYSTAL DISPLAY DEVICE - The present invention provides a liquid crystal display device having a sufficiently improved reflectance. The liquid crystal display device of the present invention is a liquid crystal display device including a pair of substrates and a liquid crystal layer sandwiched between the pair of substrates, at least one of the pair of the substrates including an insulating layer and a reflective pixel electrode for reflective display, the insulating layer including a flat part surrounding the reflective pixel electrode, convex portions under the reflective pixel electrode, and a bevel part inclining downward from the flat part between the flat part and the convex portions, the convex portions having an average diameter of 1 to 50 μm, and vertex points of the reflective pixel electrode layer on the convex portions being not lower than the flat part. | 11-08-2012 |
20130155345 | DISPLAY PANEL AND METHOD FOR PRODUCING THE SAME - A display panel has a plurality of gate terminals that are formed of a gate metal layer and a plurality of source terminals that are formed of a source metal layer, disposed alternately as seen in a plane. From each of the source terminals an intermediate region and a terminal region are provided with inorganic insulating film such that a source terminal lead formed of the source metal layer is covered therewith. The intermediate region is provided with organic insulating film such that the inorganic insulating film is covered therewith. The inorganic insulating film is smaller in thickness in the terminal region than in the intermediate region. The inorganic insulating film has an opening in the terminal region to expose at least a portion of a surface of the source terminal. | 06-20-2013 |
20130278575 | LIQUID CRYSTAL DISPLAY DEVICE - A pixel of a liquid crystal panel is constituted by three subpixels. When the gradation of the pixel can be represented by only the subpixel, with setting the gradations of the subpixels to their minimum gradations, the gradation of the subpixel is determined. When the gradation of the pixel is represented by the subpixels, with setting the gradation of the subpixel to its maximum gradation and setting the gradation of the subpixel to its minimum gradation, the gradation of the subpixel is determined so that the ratio of the transmittance of the subpixel to the transmittance of the pixel is less than a limit value. When the gradation of the subpixel cannot be determined to satisfy a condition, with setting the gradation of the subpixel to its minimum gradation, the gradations of the subpixels are determined to obtain a gradation higher than or equal to the gradation of the pixel. | 10-24-2013 |
