OPTICAL MEMBER FOR DISPLAY APPARATUS

摘要

An optical member for display device is provided to increase a shielding effect to external light and to enhance a transmittance to a display light source by forming an optical trap for absorbing and reflecting light thereon. An optical member(200) for display device includes a base material(220) and an external light shielding part(240). The external light shielding part includes a light-absorbing layer(242), The base material is made of a transparent resin and includes a plurality of wedge-shaped grooves formed at one side thereof. The light-absorbing layer is formed along an inner wall of the wedge-shaped grooves. The external light shielding part includes a light-reflecting layer(244) formed on the light-absorbing layer.
