Aspects disclosed herein relate to a diffuser plate supporter, a backlight unit, and an electronic device, in which a portion configured to support a diffuser plate in a diffuser plate supporter is made of a transparent material and a portion to be fastened to the cover bottom is made of an opaque material, so that the diffuser plate supporter can prevent light leakage from occurring on the back side of the cover bottom without interfering with light reaching the diffuser plate. In addition, through a reinforcement design for the boundary portion between the portion made of the transparent material and the portion made of the opaque material, it is possible to prevent the portions made of different materials from being separated from each other during rotational fastening of the diffusion plate supporter.

A diffuser sheet and display device having the same are provided. The diffuser sheet includes a base layer, a first skin layer on an upper surface of the base layer, and a second skin layer on a lower surface of the base layer. The base layer includes a base resin, a plurality of beads dispersed in the base resin, and a plurality of pores dispersed in the base resin.

Disclosed herein are an LED package module capable of lowering the price of manufacture by simply reducing the number of LED packages without decreasing the luminance, and a display device having the same. To this end, in an LED package module according to an exemplary embodiment of the present disclosure and a display device having the same, a plurality of LED packages is mounted on an LED module substrate in a matrix such that the LED packages are oriented in intersecting directions alternately in each of the longitudinal and lateral directions. Consequently, it is possible to increase price competitiveness by simply reducing the number of LED packages without degrading the display quality.
