Abstract

Provided is a display device ( 1 a ), including: a substrate on which a plurality of pixels are arranged in a display region; a plurality of connection pads (C) provided on one surface of the substrate; and wires connecting the plurality of pixels and the plurality of connection pads to each other, the substrate including: a panel portion in which the plurality of pixels are arranged; and a terminal portion ( 30 ) in which the plurality of connection pads are arranged, the terminal portion including: a first portion ( 32 ) continuing to a first direction side of the panel portion; and a second portion ( 34 ) opposing the first portion, the second portion being formed by bending a portion of the terminal portion, the plurality of connection pads being arranged in the first portion and the second portion.

Claims (22)

1. A display device, comprising:

a substrate on which a plurality of pixels are arranged in a display region;

a plurality of connection pads provided on one surface of the substrate; and

wires connecting the plurality of pixels and the plurality of connection pads to each other,

the substrate comprising:

a panel portion in which the plurality of pixels are arranged; and

a terminal portion in which the plurality of connection pads are arranged,

the terminal portion comprising:

a first portion continuing to a first direction side of the panel portion; and

a second portion opposing the first portion, the second portion being formed by bending a portion of the terminal portion,

the plurality of connection pads being arranged in the first portion and the second portion.

2. The display device according to claim 1 , wherein a sum of a width in a second direction, which is a direction orthogonal to the first direction, of the first portion and a width in the second direction of the second portion is greater than a width in the second direction of the panel portion.

3. The display device according to claim 1 , wherein a side surface on the first direction side of the first portion and a side surface on the first direction side of the second portion overlap in a planar view.

4. The display device according to claim 1 ,

wherein the second portion comprises:

a first sub-portion; and

a second sub-portion,

wherein the first sub-portion is connected to an edge on one side of the first portion,

wherein the second sub-portion is connected to an edge on another side of the first portion, and

wherein an edge portion on the second direction side of the first sub-portion faces an edge portion on the second direction side of the second sub-portion on the another side.

5. The display device according to claim 1 , further comprising a driver IC connected to a plurality of the connection pads, the driver IC being arranged on the terminal portion so as to avoid a boundary between the first portion and the second portion.

6. The display device according to claim 1 , wherein a surface on an opposite side to the one surface of the first portion and a surface on an opposite side to the one surface of the second portion are fixed through intermediation of a reinforcing member.
