A display panel includes an array substrate in which a plurality of pixel electrodes are arranged, and the counter substrate. A non-display area of the array substrate is provided with the transfer electrode for supplying a potential to the counter substrate. The counter substrate includes: a first film; a counter electrode placed closer to the array substrate in relation to the first film, and supplied with the potential from the transfer electrode; and an alignment film stacked on the counter electrode. The counter substrate includes first grooves provided between a display area and a transfer overlapping area overlapping with the transfer electrode, the first grooves penetrating the counter electrode and at least a portion of the first film. The first grooves extend in a first longitudinal direction, and are formed in broken line in the first longitudinal direction.

Display panel and display device

A wiring substrate includes signal input portions for inputting signals, a signal receiving portion that receives the signals input from the signal input portions, and a plurality of connection wires provides connections between the signal input portions and the signal receiving portion. The plurality of connection wires constitutes a connection wire group in which three connection wires are arranged overlapping one another with insulating layers being interposed therebetween, and the connection wire group is provided with a switching contact portion at which transmission paths of the signals respectively input to the connection wires are switched to the other connection wires.

Wiring substrate and display panel

A display panel includes: a display area in which an image is to be displayed; a non-display area in which no image is to be displayed; a first mark that is arranged in the non-display area; a second mark that is arranged in the non-display area on a layer different from a layer on which the first mark is arranged and is adjacent to or superimposed on the first mark in a plan view; a light-transmitting portion that is arranged in the non-display area in such a manner as to overlap at least the first mark in a plan view; and a light-shielding portion that is arranged in the non-display area on a side opposite to the light-transmitting portion with respect to the first mark and the second mark and overlaps the light-transmitting portion in a plan view.

Display panel

A display device includes a display section including a first substrate and a second substrate, the display section displaying an image according to an electric signal, a terminal pad electrically connecting a conductor to a signal source or a ground node, and an information code expressing optically-readable information. The second substrate has a substrate overlapping area overlapping the first substrate in a plan view and a substrate non-overlapping area not overlapping the first substrate. At least a part of the terminal pad serves as a light-transmitting portion. The terminal pad and the information code are disposed in the substrate non-overlapping area on one plate surface of the second substrate such that they overlap each other in a plan view, with the light-transmitting portion covering the information code from above.
