Abstract

Provided is a display that causes an electric field generated in a transverse or diagonal direction to drive liquid crystals and enables allocation of a contact area for a conducting connection. A transparent electrode layer is formed on a surface of a counter substrate that is opposite to a surface of the counter substrate on which the liquid crystals are disposed. The counter substrate is included in a liquid-crystal display panel. An electrode layer is formed on the rear surface of a protective plate disposed to face the counter electrode. Conductive substances are disposed between the transparent electrode layer and the electrode layer to connect the transparent electrode layer to the electrode layer. A GND connecting part provided in a surrounding area of the protective plate connects the electrode layer formed on the protective plate to, for example, a casing, thus connecting the electrode layer to the GND.

Claims5

Dependent claims

A display, comprising:

a liquid-crystal display panel including a transparent electrode layer on a display surface side, said liquid-crystal display panel displaying an image in an in-plane switching mode or a fringe-field switching mode;
a protective plate that protects said liquid-crystal display panel from said display surface side;
an electrode layer formed on a rear surface of said protective plate to correspond to an area in which said transparent electrode layer of said liquid-crystal display panel is formed and to a surrounding area of said liquid-crystal display panel, said rear surface being a surface opposite to said display surface side;
and
a conductive substance that connects said transparent electrode layer formed on said liquid-crystal display panel to said electrode layer disposed on said rear surface of said protective plate, wherein
a distance between a surface of said electrode layer facing said conductive substance and a surface of said transparent electrode layer facing said conductive substance is the same as the thickness of said conductive substance in the first part and longer than the thickness of said conductive substance in the second part.
