The present invention relates to a display apparatus which is emitting light by a light emitting diode (LED) for emitting light in a side surface, and more specifically, to an LED display board which increases illuminance distribution of a lightweight display apparatus, and increases a heat radiation effect. By making the illuminance distribution of the display apparatus uniformly to increase visibility and effectively radiate heat emitted from an LED light source, thereby increasing durability of an LED module to economically manage. |
