PROBLEM TO BE SOLVED: To reduce accumulation of heat in a light emitting layer in an organic electroluminescence display apparatus. SOLUTION: In the organic electroluminescence display apparatus 5 of the invention, a circuit board 40 is arranged to a side face 30c direction of a light emitting part 30. Therefore, as a board face of the circuit board 40 does not interrupt heat emission by facing a back face 30b of a display part 30, the accumulation of the heat is reduced in the light emitting layer 31. Also, as a heat sink plate 39 is stuck on a rear face 30b of the display part 30, the accumulation of the heat is reduced in the light emitting layer 31 with a heat radiating effect of the heat sink plate 39. Moreover, cold air is sent from a cold air supply means 60 to a ventilating pipe 61 which penetrates through the heat sink plate 39. Therefore, the heat sink plate 39 is cooled and the accumulation of the heat is reduced in the light emitting layer 31. COPYRIGHT: (C)2006,JPO&NCIPI
