Surface light source device, method of manufacturing the same and display apparatus having the same

摘要

A surface light source device includes a body, a partition member and a visible light generating unit. The body includes first and second substrates. The first substrate has a first discharge region, a first space diving region alternately formed with the first discharge region and a light transmission portion protruded from the first space dividing region. The second substrate faces the first substrate. The partition member is interposed between the first and second substrates to form a discharge space between the first and second substrates. The visible light generating unit disposed at the body generates a visible light. Therefore, dark lines displayed in a conventional display apparatus due to partition members are converted into bright lines, and the bright lines are diffused by the light diffusing patterns or the light diffusing part. Therefore, a luminance and a uniformity of the luminance are enhanced.
