The present invention relates to an optical assembly, a backlight unit, and a display apparatus thereof. According to an embodiment of the present invention, an optical assembly includes a first layer, a plurality of light sources disposed over the first layer, a second layer that is disposed above the first layer and covering the plurality of light sources, and a pattern layer disposed above or in the second layer, wherein the pattern layer includes a plurality of patterns disposed at positions substantially corresponding to the light sources.

Optical assembly, backlight unit and display apparatus thereof

The present invention relates to an optical assembly, a backlight unit, and a display apparatus thereof. According to an embodiment of the present invention, an optical assembly includes a first layer, a plurality of light sources disposed over the first layer, a second layer that is disposed above the first layer and covering the plurality of light sources, and at least one reflection layer between the first layer and the second layer, wherein the reflection layer includes at least a first portion and a second portion having different reflectances.

The present invention relates to an optical assembly, a backlight unit, and a display apparatus thereof. According to an embodiment of the present invention, an optical assembly includes a first layer; a plurality of light sources disposed over the first layer; and a second layer that is disposed above the first layer and cover the plurality of light sources on the first layer, wherein the plurality of light sources are disposed as a first light source array and a second light source array, the first light source array including first lines of light sources among the plurality of light sources, the second light source array including second lines of light sources among the plurality of light sources, the first and second lines being alternatively disposed.

A backlight unit may be provided that includes a substrate, light sources, a light guide plate, at least one reflecting member, and an optical sheet. The light sources may be on the substrate. The light guide plate may include a light incident part having a light incident surface to which streaks of light respectively emitted from the light sources are laterally incident, and a light emitting part emitting the incident streaks of light upward. The reflecting member may be disposed on a lower surface of the light guide plate, and may reflect the incident light. The optical sheet may be disposed above the light guide plate. The reflecting member may include a first region having a first reflectance and a second region having a second reflectance.
