Abstract
A display device has excellent luminous efficiency, the display device including: a display portion including pixels defined by a pixel defining layer; and a touch portion on the display portion. The touch portion includes: a first touch electrode overlapping the pixel defining layer; a first organic layer on the first touch electrode; a second touch electrode contacting the first touch electrode; a second organic layer on the second touch electrode; and a high refractive index layer on the first organic layer, the second touch electrode, and the second organic layer. The high refractive index layer is disposed between adjacent second touch electrodes in a plan view and includes a first convex surface protruding toward the display portion and overlapping one of the pixels.
