Abstract

A display device includes a first substrate having a first surface defined as a display surface and a second surface that is an opposite surface of the first surface, a second substrate disposed opposite the second surface of the first substrate, and a conductive film disposed on the second surface of the first substrate. The display surface is divided into a display area displaying an image and a non-display area displaying no image. The conductive film is disposed to overlap at least the display area and includes synthetic resin material having light transmissive properties.

Claims (18)

1 . A display device, comprising:

a first substrate having a first surface defined as a display surface and a second surface that is an opposite surface of the first surface, the display surface being divided into a display area displaying an image and a non-display area displaying no image;

a second substrate disposed opposite the second surface of the first substrate;

a conductive film disposed on the second surface of the first substrate, the conductive film being disposed to overlap at least the display area and including a synthetic resin material having light transmissive properties;

a sealing portion having a frame shape and disposed between outer peripheral edge portions of the first substrate and the second substrate;

an electrode disposed on the second substrate and on an inner side of the sealing portion, the electrode being at a ground potential; and

a connection portion disposed between the first substrate and the second substrate, on the inner side of the sealing portion, and connected to the conductive film and the electrode, wherein

the conductive film is further disposed on the inner side of the sealing portion.

2 . A display device comprising:

a first substrate having a first surface defined as a display surface and a second surface that is an opposite surface of the first surface, the display surface being divided into a display area displaying an image and a non-display area displaying no image;

a second substrate disposed opposite the second surface of the first substrate;

a conductive film disposed on the second surface of the first substrate, the conductive film being disposed to overlap at least the display area and including a synthetic resin material having light transmissive properties;

pixel electrodes;

a sealing portion having a frame shape and disposed between outer peripheral edge portions of the first substrate and the second substrate;

an electrode disposed on the second substrate and on an inner side of the sealing portion, the electrode being at a ground potential; and

a connection portion disposed between the first substrate and the second substrate, and on the inner side of the sealing portion, and connected to the conductive film and the electrode, wherein the conductive film:

is further disposed on the inner side of the sealing portion, and

is disposed in a solid manner to overlap an entirety of the display area, and to overlap the pixel electrodes.
