A shield electrode is provided in the vicinity of a pixel electrode and source bus lines. The shield electrode may be provided in the same layer as gate bus lines, or in the same layer as the source bus lines. The shield electrode may be surrounded by an insulating material, or may be connected to a line other than the source bus lines. By providing the shield electrode, it is possible to reduce a source-drain parasitic capacitance between a pixel electrode and a source bus line.

Liquid crystal display device having source-drain parasitic capacitances of a delta arrangement

A light-blocking film is formed by a resin, is formed on a surface of a first substrate that is closer to a second substrate continuously without being interrupted along a side edge of the first substrate, and is formed extending from an outer edge of a display region to the side edge of the first substrate. The first substrate is formed to be thinner than the second substrate. A region having a uniform surface height is formed on the surface of the first substrate that is closer to the second substrate along the side edge of the first substrate.

Display device

A display device includes: a plurality of signal lines which extend in a zigzag manner in a column direction and to which image signals are supplied, respectively; an insulation film which covers the plurality of signal lines; and a plurality of pixel electrodes which are formed on the insulation film and to which the image signals are input from the plurality of signal lines, respectively. A distance between ones of the pixel electrodes located adjacent to each other in the column direction is equal to or larger than a line width of the signal lines.

Display device having particular signal lines

A display device includes a source line for supplying a display signal, a display pixel electrode, and a TFT for switching an electrical connection between the source line and the pixel electrode. The TFT includes a source electrode electrically connected to the source line, a drain electrode electrically connected to the pixel electrode, and a gate electrode for controlling an electrical connection between the source electrode and the drain electrode. A first auxiliary capacitor electrode and a second auxiliary capacitor electrode are connected to the drain electrode and respective connection portions between the drain electrode and the auxiliary capacitor electrodes are formed of a semiconductor material.

Display device and method for fabricating the same

A display device of the present invention comprises: a source line; a pixel electrode; a first TFT for switching an electrical connection between the source line and the pixel electrode; and a second TFT as a spare. The second TFT includes a semiconductor film and a gate electrode. The semiconductor film includes a source electrode and a drain electrode. The gate electrode is provided on the semiconductor film with a gate insulation film interposed therebetween. The display device includes an interlayer insulation film between the source line and the semiconductor film of the second TFT. The interlayer insulation film is thicker than the gate insulation film. When the first TFT is unusable, a contact hole is formed in the interlayer insulation film such that the source line is electrically connected to the source electrode, whereby the electrical connection between the source line and the pixel electrode is rendered switchable by the second TFT.
