A layered structure includes a first electrode layer on an insulating substrate, a first insulating film on the first electrode layer, a second electrode layer on the first insulating film, a second insulating film on the second electrode layer, and a third electrode layer on the second insulating film. The first electrode layer, an opening of the first insulating film, the second electrode layer, an opening of the second insulating film, and the third electrode layer have a stack structure that causes the first electrode layer and the second electrode layer to be connected. The third electrode layer relays or reinforces, through the opening of the second insulating film, a connection between the first electrode layer and the second electrode layer formed on the first insulating film.

Layered structure, thin film transistor array, and method of manufacturing the same

A color filter having excellent display quality is provided by a continuous exposure method using a compact photomask. The color filter includes: a substrate; a black matrix formed on the substrate, for dividing the substrate into rectangular display regions in which the plurality of pixels are arrayed, and non-display regions surrounding the display regions; a stripe pattern; a plurality of columnar spacers disposed in the display regions; and a plurality of dummy columnar spacers. The stripe pattern includes a plurality of colored layers extending in one direction. Each colored layer intersects with a pair of sides of the display region in a direction perpendicular to the direction in which the colored layers extend. The thickness of both end portions of each colored layer disposed on the non-display region is not uniform. The dummy columnar spacers are disposed in portions of the non-display regions, where the colored layers are absent.

Color filter and color filter manufacturing method

In an exposure method, a photomask and a substrate having a resist applied thereto are positioned so as to be opposed to a blinking light source that repeatedly emits light and emits no light. The blinking light source is caused to blink with the substrate being continuously conveyed in a direction orthogonal to a direction in which openings in the photomask are aligned, so that multiple exposures are intermittently performed. In each exposure, a speed at which the substrate is conveyed is controlled such that the openings of the photomask overlap a portion of exposed patterns having been obtained by an immediately preceding exposure, thereby obtaining colored layers which are formed into a striped-shape and extend in the direction in which the substrate is conveyed.

Exposure method and exposure device

A liquid crystal display device is provided which prevents variation in display from being caused due to misalignment of positions of exposure heads and/or error in assembly, and which is excellent in display quality. A liquid crystal display deviceincludes: a color filterand a TFT substratewhich are bonded so as to oppose each other; and liquid crystal (not shown) sealed in a space formed therebetween. The color filterincludes: a substrate; black matrixesprovided on the substrate; and a plurality of colored layersandwhich partially overlap the black matrixesat each pixel position. Vertices of ridgesandformed by the colored layersandoverlapping the black matrixare positioned in an area where upper edgesand, respectively, which continue in the Y-axis direction, are shielded from light by a light shielding sectionof the TFT substrate

Liquid crystal display device

One embodiment of the present invention is a thin film transistor array including an insulating substrate, a plurality of thin film transistors and a sealing layer. The sealing layer is stripe-shaped and covers a plurality of the thin film transistors. The sealing layer is formed over the insulating substrate.
