Light guide plate, backlight unit having the same, display apparatus having the same, and method of manufacturing the same

A light guide plate comprising:

• a light incident surface to which a light is configured to be incident;
• a light exit surface from which the light incident through the light incident surface is configured to exit;
• a bottom surface facing the light exit surface configured to reflect at least a portion of the incident light;
• and
• a scattering pattern disposed on the bottom surface,
• wherein the scattering pattern comprises:
• a first protrusion portion having a circular shape and protruding from the bottom surface;
• a recess portion disposed along a circumference of the first protrusion portion and recessed from the bottom surface;
• and
• a second protrusion portion spaced apart from the first protrusion portion and disposed along a portion of the recess portion,
• wherein scattering pattern is divided into the first region and a second region with respect to an imaginary line crossing a center of the first protrusion portion,
• the second protrusion portion is disposed only in a first region, and
• the maximum height in a portion of the first region, which is not overlapped with the first protrusion, is higher than the maximum height in a portion of the second region, which is not overlapped with the first protrusion.
