Abstract

The invention provides an optical assembly and a display apparatus thereof. The optical assembly is provided that may include a light emitting module that includes a plurality of light emitting devices to emit light, a light guide plate, and a side cover. The light guide plate may include at least one protrusion on a top surface of a first part of the light guide plate. The side cover includes a plurality of holes to receive the at least one protrusion.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Application No. 10-2010-0001470 filed Jan. 7, 2010, the subject matter of which is hereby incorporated by reference. technical field [0003] Embodiments may relate to an optical assembly, a backlight unit having the optical assembly, and / or a display device thereof. Background technique [0004] Light emitting diodes (LEDs) can constitute light emitting sources by using GaAs-based, AlGaAs-based, GaN-based, InGaN-based, and InGaAlP-based compound semiconductor materials. [0005] LEDs may be packaged so as to be used as light emitting devices that emit light with various colors. The light emitting device may be used as a light source in various products such as lighting indicators, character indicators, and / or image indicators. [0006] A backlight unit may be provided to emit light toward the display panel, and have LEDs and a light guide plate. [0007] In a conventiona...
