Abstract
A backlight unit includes: a point light source which generates light, a light guide plate defining upper and lower surfaces thereof opposing one another, a side surface provided in plural each connecting the upper and lower surfaces to each other; and among the plural side surfaces a light-incident side surface thereof at which the point light source is disposed and on which is incident the light generated from the point light source; and a reflective side surface thereof which is adjacent to the light-incident side surface and reflects light within the light guide plate, and which forms a first angle with respect to the light-incident side surface; and a wavelength converting unit between the light guide plate and the point light source.
