Abstract: The present invention relates to a backlight unit. In the present invention, the backlight unit is constituted by attaching the pressure sensitive adhesive formulated with light scattering particles to a substrate that light emitting bodies are present. Said pressure sensitive adhesive does not cause looseness, peel-off and curl even in a severe condition such as high temperature or high temperature and high humidity as well as a phenomenon such as yellowing or whitening. Therefore, the present invention may provide a unit having high brightness and excellent luminance uniformity, overcoming step height due to the light emitting body and having thin thickness, and is also advantageous to be applied to a flexible device.
