Abstract

A display device includes a first substrate on which a thin film transistor is formed and which is divided into a display area and a non-display area outside thereof, a second substrate arranged to face an upper surface of the first substrate, a light-shielding film provided in an area between the first substrate and the second substrate, and a circuit provided on an upper surface of the second substrate and in an area facing the display area. The second substrate includes a terminal part of the circuit, which is provided on the upper surface of the second substrate and in an area facing the non-display area. The terminal part is connected with a circuit driving substrate, which drives the circuit through an anisotropic conductive film covering the terminal part. The light-shielding film is provided to avoid at least part of an area facing the terminal part.

Claims (17)

1. A display device comprising:

a first substrate on which a thin film transistor is formed and which is divided into a display area and a non-display area outside thereof;

a second substrate arranged to face an upper surface of the first substrate;

a light-shielding film provided in an area which is between the first substrate and the second substrate and faces over the display area to be extended over the non-display area; and

a wiring provided on an upper surface, which is opposite to the first substrate, of the second substrate and in an area facing the display area, wherein

the second substrate includes a terminal part of the wiring, which is provided on the upper surface of the second substrate and in an area facing the non-display area,

the terminal part is connected with a wiring substrate, through an anisotropic conductive film covering the terminal part, and

the light-shielding film is provided to avoid at least part of an area facing the terminal part.

2. The display device according to claim 1 , wherein the light-shielding film is provided with an opening to avoid the area facing the terminal part.

3. The display device according to claim 2 , wherein

another wiring is provided in the non-display area of the first substrate and

the wiring sitting in the non-display area of the first substrate is provided to avoid an area facing the opening.

4. The display device according to claim 3 , wherein the opening is provided in at least three portions which are, in an extension direction of the area where the terminal part is provided, areas corresponding to both ends of the area where the terminal part is provided and an area corresponding to a middle of both the ends.

5. The display device according to claim 2 , wherein the opening is provided in at least three portions which are, in an extension direction of the area where the terminal part is provided, areas corresponding to both ends of the area where the terminal part is provided and an area corresponding to a middle of both the ends.

6. The display device according to claim 2 , wherein

another wiring is provided in an area facing the opening and

the wiring provided in the area facing the opening is translucent.
