Abstract

The application discloses an optical member, a manufacturing method thereof and a display device including the optical member. The optical member includes a light guide plate including an upper surface, a lower surface facing the upper surface, a first side surface disposed between the upper surface and the lower surface, a first inclined surface disposed between the upper surface and the first side surface, and a second inclined surface disposed between the lower surface and the first side surface, and a first reflective member including a first side portion covering the first side surface, afirst folded portion extending from the first side portion to one side thereof and covering the first inclined surface, and a second folded portion extending from the first side portion to the otherside thereof and covering the second inclined surface, in which the first reflective member includes a reflective layer having at least one curved surface.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2019-0039084 filed on April 3, 2019, which is hereby incorporated by reference for all purposes as if fully set forth herein. technical field [0003] Exemplary embodiments of the present invention generally relate to an optical member, a method of manufacturing the same, and a display device including the optical member. Background technique [0004] The liquid crystal display receives light from the backlight assembly and displays images. Some backlight accessories include light sources and light guides. The light guide plate receives light from the light source, and guides the light to travel toward the display panel. Some backlight assemblies use supplied white light as a light source and filter the white light through color filters on the display panel to implement color. [0005] Recently, the application of wavelength conversio...
