The present disclosure provides a display device including a substrate, an encapsulation layer over the substrate, a touch sensor layer on the encapsulation layer and including a plurality of touch sensors, and a transmittance control layer on or under the touch sensor layer.

Display device

Embodiments of the disclosure relate to a wavelength control film and a display device. A wavelength control layer for absorbing part of light of a specific wavelength band is disposed on an outer surface of a transparent substrate of the display device to enable a correction to the color temperature of white light, thus allowing for high-efficiency driving and a high color gamut upon implementing white light. Further, adjustment of the light absorption peak wavelength and transmittance of the light absorption material included in the wavelength control film enables wavelength control, with the characteristics of the light emitting element considered, and reduce external light reflectivity to thus provide the functions of a polarization plate.
