Abstract
A light source and a display device having the same are provided. The light source may include light guide plates arranged in rows and columns, light emitting diodes (LEDs) positioned below the light guide plates to direct light toward lateral surfaces of the light guide plates, and module substrates that support and provide power to the LEDs. Each of the light guide plates may include a first region divided into a plurality of second regions. LEDs corresponding to each of the second regions may be operated as a unit and independently from other regions.
