Optical member and display including the same

An optical member comprising:

• a light guide plate in which light incident thereto is propagated, including:
• an emission surface through which propagated light exits the light guide plate,
• a light incident side surface through which the light is incident to the light guide plate, and
• an inclined edge surface connecting the emission surface and the light incident side surface to each other;
• a wavelength conversion layer to which exited light from the light guide plate is incident and which converts a wavelength of the exited light, disposed facing the emission surface of the light guide plate;
• and
• a light adjustment member with which a path of light is adjusted to be incident into the light guide plate, disposed facing the inclined edge surface of the light guide plate and spaced apart from the wavelength conversion layer,
• wherein
• a first region of the light guide plate extends from the light incident side surface thereof to an end of the light adjustment member furthest from the light incident side surface,
• a second region of the light guide plate extends from the first region in a direction away from the light incident side surface and includes the wavelength conversion member facing the emission surface of the light guide plate, and
• a thickness of the light adjustment member with respect to the light guide plate is maximum at a boundary between the first region and the second region of the light guide plate.

An optical member comprising:

• a light guide plate in which light incident thereto is propagated, including:
• an emission surface through which propagated light exits the light guide plate, and
• a light incident side surface through which the light is incident to the light guide plate;
• a refractive layer which is disposed facing the emission surface of the light guide plate and receives light exited therethrough, a refractive index of the refractive layer being smaller than that of the light guide plate;
• a wavelength conversion layer to which light from the refractive layer is incident and which converts a wavelength of the light incident thereto, disposing the refractive layer between the emission surface of the light guide plate and the wavelength conversion layer;
• a passivation layer to which light from the wavelength conversion layer is incident and through which light exits from the optical member, disposed covering a side surface of the refractive layer and a side surface of the wavelength conversion layer;
• and
• an angle filter disposed on the light incident side surface of the light guide plate,
• wherein the angle filter reflects light having an incident angle equal to or larger than a first angle with respect to the light incident side surface of the light guide plate and passes light having an incident angle smaller than the first angle.
