Abstract: A display device includes a display panel in which a plurality of active areas including a first active area and a second active area is defined. The device includes a plurality of sub-pixels disposed in each of the plurality of active areas, and a gate driver disposed on the plurality of active areas. Each of the plurality of sub-pixels includes a first light-emitting diode (LED) that emits light in response to a driving current and a first lens that refracts the light emitted from the first LED and a second LED that emits light in response to the driving current and a second lens that refracts the light emitted from the second LED and has a different shape from the first lens. Accordingly, the device can operate in any one of a private mode and a share mode by using the first lens and the second lens.

Abstract: Embodiments of the present disclosure relate to a transparent touch display device, and more particularly, to a transparent display device including a touch electrode having a low reflection structure. The touch electrode having the low reflection structure may include a mesh type sensor metal formed a plurality of openings, a sensor transmission layer on the sensor metal, and a sensor auxiliary metal on the sensor transmission layer. Part of the incident light incident on the upper surface of the sensor auxiliary metal is reflected from the upper surface of the sensor auxiliary metal, and another part of the incident light incident on the upper surface of the sensor auxiliary metal is reflected from the upper surface of the sensor metal after passing through the sensor auxiliary metal and the sensor transmission layer.
