    Abstract: To provide a thin touch panel, a touch panel with high visibility, a lightweight touch panel, or a touch panel with low power consumption. A pair of conductive layers included in a capacitive touch sensor have a mesh shape including a plurality of openings. Furthermore, a material blocking visible light is provided to overlap with a region between two display elements in a plan view; thus, a light-blocking layer can be obtained. Furthermore, the pair of conductive layers included in the touch sensor are provided between a pair of substrates included in the touch panel, and a conductive layer capable of supplying a constant potential is provided between a circuit which drives a display element and the pair of conductive layers.

    Abstract: In a light-emitting device where reflective electrodes are regularly arranged, occurrence of interference fringes due to reflection of light reflected by the reflective electrode is inhibited. A surface of the reflective electrode of a light-emitting element is provided with a plurality of depressions. The shapes of the plurality of depressions are different from each other and do not have rotational symmetry. Irregularity of the surface shape of the reflective electrode is increased, which inhibits interference of light reflected by the reflective electrode. To form the plurality of depressions in the surface of the reflective electrode, for example, a surface of an insulating layer that is a base of the reflective electrode is made uneven. Reflecting the surface shape of the insulating layer, the reflective electrode has an uneven surface.
