ABSTRACT:
A liquid crystal display apparatus includes an optical sheet for uniformly diffusing light toward a light-emitting face, and a resin frame onto which the optical sheet is attached. The optical sheet has the first fixing portion or the second fixing portion. The optical sheet is attached to the resin frame by fitting the first fixing portion or the second fixing portion to a concavity created at the resin frame at a part corresponding to the first fixing portion or the second fixing portion. At least one notch is created at a boundary area between a display area of the optical sheet and the first fixing portion or the second portion so that deformation in the optical sheet caused by a significant mechanical stress, such as drop impact, does not extend to the display area.
