Abstract

An electronic device includes a display layer comprising emission areas that provide different colored light, respectively, and a non-emission area adjacent thereto. A sensor layer comprises a first sensing insulating layer, a first conductive layer, a second sensing insulating layer, and a second conductive layer and comprising mesh lines extending in first and second directions. The mesh lines comprise a first line extending in the first direction, second and third lines extending in the second direction from opposite sides of the first line, and a fourth line spaced apart from the third line in the first direction and extending in the second direction from the first line. A reinforcing pattern is disposed on inner areas defined by the first line and each of the second to fourth lines, respectively. The reinforcing pattern protrudes from portions of the first to fourth lines that define each inner area of the inner areas.
