Abstract
One embodiment of the present invention provides a highly reliable display device. In particular, a display device to which a signal or a power supply potential can be supplied stably is provided. Further, a bendable display device to which a signal or a power supply potential can be supplied stably is provided. The display device includes, over a flexible substrate, a display portion, a plurality of connection terminals to which a signal from an outside can be input, and a plurality of wirings. One of the plurality of wirings electrically connects one of the plurality of connection terminals to the display portion. The one of the plurality of wirings includes a first portion including a plurality of separate lines and a second portion in which the plurality of lines converge.

A display device comprising:
- a flexible substrate;
- a display portion over the flexible substrate;
- a connection terminal to which a signal from an outside is input, over the flexible substrate;
- and
- a wiring electrically connecting the connection terminal with the display portion, over the flexible substrate,
- wherein the wiring includes a first wiring and a second wiring,
- wherein each of the first wiring and the second wiring includes a first portion and a second portion,
- wherein the first portion has a same width as the second portion,
- wherein at least two openings are opened in the first portion, and
- wherein the flexible substrate can be bent in a region overlapping with the first portion.
