Abstract
A display device comprises a display panel and a backlight unit. The backlight unit comprises: a bottom cover; a light source module mounted on the bottom cover and including: light sources arranged at uniform intervals; and a circuit board on which the light sources are mounted; a reflective layer placed above the light source module to reflect the light emitted from the light sources towards the display panel; a screening layer disposed over the reflective layer at a distance therefrom and having patterned holes to allow only a portion of the light reflected from the reflective layer to be transmitted; and a spacer disposed between the reflective layer and the screening layer to form a light guide layer defined by a vacant space between the reflective layer and the screening layer and to maintain the uniform height of the light guide layer.
