Abstract:
1. A touch panel comprising: a microstructure over a first substrate, the microstructure comprising a lower electrode, an upper electrode over the lower electrode and a filler layer between the lower electrode and the upper electrode; a thin film transistor over the first substrate, the thin film transistor comprising a gate electrode and a semiconductor layer; a conductive layer over the first substrate, the conductive layer being in contact with the semiconductor layer; an insulating layer over the thin film transistor; a light-emitting element over the first substrate, the light-emitting element comprising a first electrode electrically connected to the conductive layer and over the insulating layer, a light-emitting layer over the first electrode and a second electrode over the light-emitting layer; a partition wall for covering an end portion of the first electrode and the microstructure, the partition wall having an opening overlapping with the filler layer; and a spacer over the upper electrode, the spacer overlapping with the filler layer, wherein the spacer is provided so as to fill the opening in the partition wall, wherein the microstructure does not overlap with the light-emitting layer, wherein the first electrode of the light-emitting element and the upper electrode of the microstructure are spaced from each other, wherein the lower electrode is formed using the same material as the gate electrode, and wherein the upper electrode is formed using the same material as the first electrode.
