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.
