Abstract

A display device includes: a first substrate; a second substrate overlapping a portion of the first substrate; and a driver integrated circuit arranged in a non-overlapping area, which does not overlap with the second substrate, of the first substrate. The second substrate includes a side facing the driver integrated circuit, an integrated-circuit-opposed area on the second substrate formed along a line segment opposed to the driver integrated circuit in the side, and a terminal forming area being on the second substrate formed along the side and being different from the integrated-circuit-opposed area. A terminal of the second substrate is formed only in the terminal forming area.

Claims

a first substrate including a thin film transistor;

a second substrate overlapping a portion of the first substrate and including an electrode and a terminal connected to the electrode; and

a driver integrated circuit arranged in a non-overlapping area, which does not overlap with the second substrate, of a surface of the first substrate, the surface facing the second substrate, wherein

the second substrate includes

a side facing the driver integrated circuit,

an integrated-circuit-opposed area on the second substrate formed along a line segment opposed to the driver integrated circuit, the line segment being a part of the side, and

a terminal forming area being on the second substrate, disposed along the side, and being different from the integrated-circuit-opposed area, and

the terminal of the second substrate is formed only in the terminal forming area.

4. The display device according to claim 2, wherein

the terminal forming area is formed at at least two places so as to interpose the integrated-circuit-opposed area therebetween,

the flexible substrate includes a recess so that the flexible substrate overlaps the terminal forming areas but does not overlap the integrated circuit, and

the integrated circuit is located so as to be interposed into the recess.

5. The display device according to claim 4, wherein

the flexible substrate includes a plurality of the recesses.

6. The display device according to claim 1, wherein

the electrode is used for touch detection.

7. The display device according to claim 1, wherein
