摘要： A color filter substrate includes a light transmissive substrate, a light blocking layer, a light transmissive layer, and a color layer. The light blocking layer is formed on the light transmissive substrate. The light transmissive layer is formed along an edge of the light blocking layer on the light transmissive substrate. The color layer passes rays of visible light and is tinted a predefined color so that the rays passing therethrough exhibit a predefined color. The color layer includes a section disposed on a top surface of the light transmissive substrate in a blank area and an edge section extending from the section in the blank area over the light transmissive layer and a section of the light blocking layer. A thickness of a section of the light transmissive layer on a blank area side is less than a thickness of the light blocking layer.

摘要： A liquid crystal display device includes a first substrate, a second substrate, a liquid crystal layer, and a columnar spacer. The first substrate includes a pixel electrode, a TFT, and an interlayer insulating layer. The second substrate includes first, second and third color filters arranged in a delta arrangement. Each pixel has a substantially polygonal shape with n vertices (where n is an integer and n≧8) or a substantially circular shape. The TFT and the columnar spacer are arranged in a first tricolor boundary region. A contact hole cut through the interlayer insulating layer is arranged in a second tricolor boundary region. Two of three pixels that define the first tricolor boundary region also define the second tricolor boundary region, but the remaining pixel is arranged at a different location.

摘要： A liquid crystal panel includes an array substrate, a counter substrate, and a liquid crystal layer therebetween. The counter substrate includes a sub-pixel in-between light blocking section extending in a grid and surrounding the sub pixels, a first projection projecting from the counter substrate toward the array substrate and having a projecting end that is contacted with a part of the array substrate to define a distance between the substrates, and second projections projecting from the counter substrate toward the array substrate and having projecting ends that are spaced from the array substrate. The first projection and the second projections overlap the sub-pixel in-between light blocking section. A distance between a center line of a width dimension of the sub-pixel in-between light blocking section and a center of each second projection is smaller than a distance between the center line and a center of the first projection.

摘要： A display device with a position input function includes pixel electrodes, signal lines, a common electrode, a position detection electrode, and position detection lines. The signal lines are disposed adjacent to the pixel electrodes. The common electrode is disposed to overlap the pixel electrodes via an insulating film. The position detection lines are connected to the one position detection electrode via a contact hole formed in the insulating film that is disposed between the common electrode and the position detection lines. Each of the position detection lines is disposed between the signal line and the pixel electrode such that two of the position detection lines sandwich the pixel electrodes and the signal lines. An interval between two of the signal lines that sandwich the pixel electrodes and the position detection lines is larger than an interval between two of the signal lines that sandwich the pixel electrodes.
