Abstract:
1. A display comprising: a light source; a display panel having a display region that provides images to an observer using light from the light source and non-display region in which images are not displayed; and an optical sheet through which light from the light source passes and having a hardened part, wherein the hardened part has a longitudinal axis spaced a distance from a nearest edge of the optical sheet disposed parallel to the longitudinal axis, wherein the hardened part is integral to the optical sheet, and the optical sheet comprises a non-display region in which the hardened part is formed, wherein the hardened part comprises a bent section bent by a predetermined angle and a convex part with a cylindrical shape, wherein the convex part projects towards the display panel, wherein the bent section with a line shape is bent towards the display panel and is formed in the non-display region of the optical sheet, which overlaps the non-display region of the display panel, wherein the bent section is formed in at least one side of the non-display region of the optical sheet, wherein the predetermined angle is about 20° to about 90°, wherein the optical sheet having the hardened part further comprises a cutting line for cutting a portion of the optical sheet to separate the non-display region of the optical sheet into a plurality of hardened patterns, wherein the cutting line is perpendicular to the hardened part in at least one side of the optical sheet, the side most proximate to the light source, wherein the hardened part is formed in the edge portion of the optical sheet during cutting processing of the optical sheet, and wherein the cutting line minimizes a non-uniform distance between a lower polarization plate and the optical sheet.
