An active matrix substrate includes a plurality of pixel electrodes arranged in a matrix; and a source wiring running in a column direction, wherein the source wiring includes a first side portion running along one side in a column direction of at least one pixel electrode of the plurality of pixel electrodes, a crossing portion running across the pixel electrode, and a second side portion running along another side in the column direction of the pixel electrode, the first side portion and the second side portion are connected to each other via the crossing portion, and at least one crossing portion is provided on each of at least two pixel electrodes aligned in the column direction out of the plurality of pixel electrodes.

Active matrix substrate and liquid crystal display device

At least either a first substrate or a second substrate has regions corresponding to subpixels () and provided with ribs () for controlling how a liquid crystal material is aligned. Scanning signal lines () and picture element electrodes () are overlapped with each other via an insulating material as seen in plan view. The ribs () and the scanning signal lines () are at least partially overlapped with each other as seen in plan view.

Liquid crystal display device

A liquid crystal display panel includes a color filter substrate with four or more color layers of different colors and a light shielding layer, each pixel including a repeating unit composed of the four or more color layers overlap overlapping the light shielding layer, the liquid crystal display panel having a region where color layers of the same color in different pixels are arranged in the same rows or the same columns, and a color layer of a color with higher brightness overlaps a portion of the light shielding layer positioned between the color layer and another color layer of the same color with an overlapping width smaller than that with which a color layer of a color with lower brightness overlaps a portion of the light shielding layer positioned between the color layer and another color layer of the same color.

Liquid-crystal display panel

A liquid crystal display device in which lengths (dand1 d) of respective picture element electrodes () in an extended direction of scanning signal lines () are longer than lengths (d) of the respective picture element electrodes () in an extended direction of video signal lines () is arranged such that storage capacitor lines () are provided along the respective scanning signal lines () so as to overlap the respective picture element electrodes () via an insulating film () in plan view.

Liquid crystal display device utilizing storage capacitor lines

Each of picture elements () has a plurality of alignment regions (RRRand R), in each of which liquid crystal molecules contained in a liquid crystal layer are aligned in a direction that is different from those in the others of the plurality of alignment regions. Each of a plurality of scanning signal lines () and a border region (Rand R) between corresponding adjacent ones of the plurality of alignment regions (RRRand R) at least partially overlap each other when viewed from above.

It is an object of the invention to provide a display and a method for repairing defects of the same in which defects such as inter-layer short-circuits and short-circuits in a single that have occurred at steps for manufacturing the display can be easily repaired to provide a good product with a probability higher than that in the related art. Laser irradiation is carried out as a first cycle of laser irradiation by forming a slit Sin a region where a drain bus linecompletely covers a gate bus lineto form a cut portion longer than the width of the gate bus lineadjacent to an inter-layer short-circuitsuch that it splits an intersecting portion of the drain bus lineinto two parts as shown in FIG.Next, as shown in FIG.slits Sand Sare respectively used for second and third cycles of laser irradiation to cut the drain bus lineat both ends of the cut portion (indicated by S), thereby isolating the inter-layer short-circuitof the drain bus line
