PURPOSE: An LED flat illuminator is provided to control the amount of spot light by forming a reflection layer and an absorbing layer on the inner side of an optical guide. CONSTITUTION: A plurality of light emitting diodes(210,220) are formed in a base substrate(100). A plurality of light emitting diodes are white LEDs and color LEDs. An optical guide(300) surrounds at least one light emitting diode from the plural light emitting diode to radiate spot light. The optical guide unit surrounds the color LED and includes a partition wall dividing the inside of the optical guide. |
