Abstract: A manufacturing method of a backlight unit includes: providing a light emission surface of a light guide plate to include contact areas and a cavity area between contact areas; forming first sacrifice patterns at the cavity area to have a same width as each other; forming a first insulation layer on the first sacrifice patterns and extended to contact the light emission surface at the contact areas; removing the first sacrifice patterns to form a cavity between the light emission surface and the first insulation layer, at the cavity area; and with the cavity at the cavity area, forming a second insulation layer at the cavity area and at the contact areas. The contact areas are arranged spaced apart from each other in the first direction, and a number of the first sacrifice patterns at the cavity area decreases as a distance in the first direction increases.
