There is provided a liquid crystal display (LCD) device that prevents light leaks near spacers. The LCD device controls the optical transmissivity of a liquid crystal layer interposed between substrates disposed opposite each other, by means of an electric field generated in the layer-thickness direction of the liquid crystal layer. The LCD device includes spacers on a liquid-crystal-side surface of one substrate, signal lines formed on a liquid-crystal-side surface of the other substrate, an insulating film formed to cover the signal lines, and electrodes on the insulating film's upper surface. Each electrode contributes to controlling the optical transmissivity of the liquid crystal layer. Each spacer has a vertex surface disposed opposite to the signal lines. A portion of each electrode extends to the upper surface of a corresponding signal line. The extended portion is opposite to a part of a spacer's vertex surface disposed opposite to the corresponding signal line.

Liquid crystal display device

Image display device having an electrode forming layer which includes a plurality of gate lines, a plurality of drain lines, a plurality of switching elements and the a plurality of pixel electrodes, and having reference electrode layer between the electrode forming layer and a substrate where the electrode forming layer formed thereon, and the reference electrode layer and the electrode forming layer are insulated by insulating layer.

Liquid crystal display device, display device and manufacturing method thereof

A liquid crystal display includes a first substrate and a second substrate opposed to each other with liquid crystal therebetween. A first pixel including a first TFT element and a first pixel electrode formed of a transparent conducting layer and disposed over the first substrate. A second pixel, adjacent to the first pixel, including a second TFT element and a second pixel electrode formed of a transparent conducting layer and disposed over the first substrate. A gate signal line disposed over the first substrate, is connected to the first and the second TFT elements. A drain signal line disposed over the first substrate and between the first and the second pixel electrodes, is connected to the second TFT element. A counter electrode formed of a transparent conducting layer and disposed over the first substrate, and is overlapped with the first and the second pixel electrodes and the drain signal line.

A liquid crystal display includes a first substrate and a second substrate opposed to each other with a liquid crystal layer between the first substrate and the second substrate. The first substrate has a plurality of drain signal lines and a plurality of gate signal lines, and a plurality of pixel regions are defined by the drain signal lines and the gate signal lines. Each of the pixel regions includes a first electrode having a plurality of strip-like portions extending in an extension direction of the drain signal lines, the strip-like portions having at least one bent portion so that extension directions of each two parts of the strip-like portions separated by the at least one bent portion are different from each other, and a second electrode formed between the first substrate and the first electrode, and being overlapped with the strip-like portions in plan view.
