Abstract

According to an aspect, a display device with a sensor includes: a substrate including a display region and a peripheral region on a periphery of the display region; detection electrodes arranged in a row-column configuration in the display region; and detection lines coupled to the respective detection electrodes. A shape of the substrate in a plan view includes a curve of a curved portion. The detection electrodes include a first electrode and a second electrode having a shape different from that of the first electrode in a plan view. The second electrode is juxtaposed with the curved portion. The detection lines each include a first line coupled to the first electrode and a second line coupled to the second electrode. The second line passes from the display region across the peripheral region and extends to a position overlapping with the second electrode in a plan view.

Claims (24)

1. A display device comprising:

a plurality of detection lines arrayed in a first direction with a space therebetween, the detection lines each extending in a second direction;

a plurality of detection electrodes arrayed in the second direction, the detection electrodes including a first detection electrode and a second detection electrode; and

a connection linear portion,

wherein

the detection lines are arranged in a first metal layer,

each of the detection lines is connected to a corresponding one of the detection electrodes,

the detection lines include a first detection line connected to the first detection electrode and a second detection line connected to the second detection electrode,

the second detection line includes a first linear portion, a second linear portion, and a third linear portion,

the first linear portion extends in the second direction and is located on a first side of the second detection line in the first direction,

the second linear portion extends in the second direction and is located on a second side of the second detection line in the first direction, the second side being an opposite to the first side,

a tip of the second linear portion in the second detection line and a tip of the first detection line in the second direction are aligned along the first direction,

the third linear portion extends in the first direction and connects the first linear portion and the second linear portion,

the third linear portion is located outside the tip of the first detection line without crossing the first detection line,

the connection linear portion is formed in a second metal layer that is different from the first metal layer,

the tip of the first detection line is connected to the connection linear portion, and

the connection linear portion crosses the third linear portion.

2. The display device of claim 1 , wherein

an area of the first detection electrode is different from an area of the second detection electrode.

3. The display device of claim 2 , wherein an area of the second detection electrode is smaller than an area of the first detection electrode.

4. The display device of claim 1 , further comprising an organic insulating film, wherein

the organic insulating film includes a first surface and a second surface opposed to the first surface,

the detection electrodes are formed on the first surface, and

the detection lines are formed on the second surface.
