Display device

A display device, comprising:

• a substrate;
• a plurality of light emitting diodes (LEDs) on the substrate;
• an encapsulation layer on the plurality of LEDs;
• a touch sensor unit on the encapsulation layer;
• and
• a lens layer on the touch sensor unit,
• wherein the touch sensor unit includes:
• a plurality of bridge electrodes on the encapsulation layer;
• an optical gap layer on the bridge electrodes to expose at least a part of each of the plurality of bridge electrodes;
• and
• a touch electrode in contact with each of the plurality of exposed bridge electrodes, and
• the optical gap layer includes:
• a sub-lens layer disposed corresponding to the plurality of LEDs;
• a cylindrical structure layer on the sub-lens layer to correspond to the plurality of LEDs;
• and
• an overcoating layer on the sub-lens layer and the cylindrical structure layer,
• wherein a plurality of sub-pixels is defined on the substrate,
• wherein each of the plurality of sub-pixels includes a first LED and a second LED on the substrate, and
• wherein the lens layer includes a first lens that refracts light from the first LED and a second lens that refracts light from the second LED.
