Abstract: An erroneous operation is made less likely to occur in a portable electronic device including a touch panel. The portable electronic device has a plate-like external shape. An organic EL display panel that displays an image on a display surface is disposed on one surface of the external shape. A touch sensor is disposed on the display surface and detects contact of an object with the display surface. As the touch sensor, a capacitive contact sensor is disposed in a main area of the display surface that is set to include a central portion, and a resistive contact sensor is disposed in a side area of the display surface that includes at least a portion of an edge of the display surface and is set exclusively of the main area.

Each of the plurality of pixels includes: a transistor above the insulating surface; a planarization film covering the transistor; a pixel electrode above the planarization film and electrically connected with the transistor; an insulating layer filled in a recess located around the pixel electrode between the pixels adjacent to each other; a light-emitting layer covering a surface of the pixel electrode and at least a part of a surface of the insulating layer; and a counter electrode above the light-emitting layer. A distance between a surface of the substrate and a face of the light-emitting layer in contact with the insulating layer is equal to or smaller than a distance between the surface of the substrate and a face of the light-emitting layer in contact with the pixel electrode.
