    Abstract: An optical film is provided. The optical film includes a base film and a cover film. The base film includes a base member and a plurality of lens patterns disposed on the base member. The plurality of lens patterns protrudes from the base member and extends in a first direction. The cover film is disposed on the base film to cover the base member and the plurality of lens patterns. A refractive index of at least one of the lens patterns is smaller than a refractive index of the cover film. An aspect ratio of the at least one of the lens patterns ranges from 0.8 to 1.6.

    Abstract: A display device includes a display portion including a first surface, from which light is emitted in a first direction, and a second surface opposite to the first surface, a first optical portion disposed on the first surface, and a second optical portion disposed on the first surface to be spaced apart from the first optical portion in a second direction crossing the first direction. Each of the first and second optical portions includes a multi-channel lens through which the light from the first surface passes, a first infrared light source, a first camera, and a first lens frame coupled to the multi-channel lens in the first direction to support at least a portion of the multi-channel lens. The first lens frame may include a first recess structure in which the first infrared light source is disposed and a second recess structure in which the first camera is disposed.
