Optical sheet and display device having the same

摘要

An optical sheet includes a base layer, a light-condensing layer and a plurality of light-reflecting portions. The light-condensing layer includes a plurality of light-condensing portions formed on a second surface of the base layer along a first direction crossing a longitudinal side and a vertical side of the optical sheet that meet each other at the second surface. The light-condensing portions are extended in a second direction crossing the first direction to be tilted with respect to the longitudinal side and the vertical side. The light-reflecting portions are formed in the first surface corresponding to a plurality of recesses where the light-condensing portions meet each other to be formed in the second direction. The center of the light-reflecting portion is spaced apart from the recessed in the first direction. Thus, a plurality of optical sheets such as a diffusion sheet and a light-condensing sheet may be omitted.
