Abstract: The first and second touch electrodes constitute a mesh shape of staying away from overlap with the light-emitting pixels. Each electrode body has a first slim portion between adjacent light-emitting pixels in the first direction. Each electrode body has a first wide portion between adjacent light-emitting pixels in the second direction. The first wide portion is wider than the first slim portion. The jumper electrode has a second slim portion between adjacent light-emitting pixels in the first direction. The jumper electrode has a second wide portion between adjacent light-emitting pixels in the second direction. The second wide portion is wider than the second slim portion. The light-emitting pixels each have a planar shape longer in the second direction than in the first direction. The first and second wide portions are overlapped and electrically conductive, penetrating the insulation film.
