Patent ID: 8256948

Claim:
A light emitting diode display device comprising: a plurality of light emitting diodes; and a light guide unit for guiding a light beam emitted by each of the plurality of light emitting diodes, wherein the plurality of light emitting diodes are respectively arranged in such a manner that the light emitting surface of each of the light emitting diodes faces the light guide unit, and that the light beams emitted by the respective light emitting diodes are prevented from intersecting each other, and wherein a plurality of emitting sections are provided on one surface of the light guide unit, wherein a first light emitting diode and a second light emitting diode of the plurality of light emitting diodes are arranged in such a manner that the first light emitting diode and the second light emitting diode are respectively arranged at diagonal position with respect to the light guide unit when viewed from the direction of light beam emitted from the light guide unit, that the traveling direction of the light beam emitted by the first light emitting diode to the light guide unit is opposite to the traveling direction of the light beam emitted by the second light emitting diode to the light guide unit, that the central axes of the light beams emitted by the respective light emitting diodes are inclined with respect to the vertical axis of the light incident surface of the light guide unit, and that the central axes of the light beams emitted by the respective light, and wherein the light guide unit has a first side and a second side opposite the first side, the first light emitting diode positioned at the first side of the light guide unit, and the second light emitting diode positioned at the second side of the light guide unit.
