Abstract

A display apparatus includes: a first substrate and a second substrate arranged so as to face each other; a display region included in each of the first substrate and the second substrate; a transparent region formed inside the display region in a planar view; a frame region formed between the display region and the transparent region so as to surround the transparent region along an outer edge of the transparent region in a planar view; a polarizer formed in either the first substrate or the second substrate and having an opening overlapping the transparent region; a first transparent conductive film formed in a first conductive layer between the first substrate and the second substrate; and a second transparent conductive film formed in a second conductive layer between the first conductive layer and the second substrate. The second transparent conductive film is in the frame region in a planar view.

Claims (35)

1. A display device comprising:

a first substrate and a second substrate arranged to face each other;

a display region included in each of the first substrate and the second substrate;

a transparent region formed inside the display region in a planar view;

a frame region formed between the display region and the transparent region to surround the transparent region along an outer edge of the transparent region in a planar view;

a polarizer formed on either the first substrate or the second substrate and including an opening overlapping the transparent region;

a first transparent conductive film formed in a first conductive layer between the first substrate and the second substrate;

a second transparent conductive film formed in a second conductive layer between the first conductive layer and the second substrate; and

an alignment film covering the second conductive layer,

wherein the second conductive layer is between the first conductive layer and the alignment film, and

in plan view, the second transparent conductive film overlaps an entirety of the transparent region.

2. The display apparatus according to claim 1 ,

wherein in the transparent region, the alignment film contacts the second transparent conductive film.

3. The display apparatus according to claim 2 ,

wherein in plan view, the frame region forms a ring shape, and the second transparent conductive film is circular along the ring shape.

4. The display apparatus according to claim 3 ,

wherein the second conductive layer includes a plurality of portions separated from each other through a slit formed in a ring shape along the ring shape of the frame region, and

the second transparent conductive film that is circular-shaped is a portion of the plurality of portions formed inside the slit.

5. A display device comprising:

a first substrate and a second substrate arranged to face each other;

a display region included in each of the first substrate and the second substrate;

a transparent region formed inside the display region in a planar view;

a frame region formed between the display region and the transparent region to surround the transparent region along an outer edge of the transparent region in a planar view;

a polarizer formed on either the first substrate or the second substrate and including an opening overlapping the transparent region;

a first transparent conductive film formed in a first conductive layer between the first substrate and the second substrate;

a second transparent conductive film formed in a second conductive layer between the first conductive layer and the second substrate; and

an alignment film covering the second conductive layer,

wherein in plan view, the second transparent conductive film includes a plurality of portions separated from each other through a slit,

the second conductive layer is between the first conductive layer and the alignment film,

in the transparent region, the alignment film contacts each of the plurality of portions of the second transparent conductive film, and

an entirety of the transparent region overlaps either the second transparent conductive film or the slit.

6. The display apparatus according to claim 5 ,

wherein in plan view, the frame region forms a ring shape, and the plurality of portions of the second transparent conductive film is are arranged to form a circle along the ring shape of the frame region,

in plan view, the second transparent conductive film is divided into four portions via a first slit extending through the aperture of the polarizer in a first direction or a second slit extending through the aperture of the polarizer in a second direction crossing the first direction, and

the entirety of the transparent region overlaps any of the second transparent conductive film, the first slit, or the second slit.
