PROBLEM TO BE SOLVED: To provide an LED display device for supporting various kinds of color lights by a user's choice.SOLUTION: An LED display device 100 includes: an LED substrate 110 on which a plurality of LED elements 112 generating light of a first wavelength are arranged in rows and columns; a first light conversion sheet 120 which is located on the upper part of the LED substrate 110, and in which punched first light transmission parts 124 are formed; and a second light conversion sheet 130 which is located on the upper part of the first light conversion sheet 120, and in which punched second light transmission parts 134 are formed. The light of at least one LED element out of the plurality of LED elements 112 emits light of a second wavelength via the first light conversion sheet 120, and the light of the second wavelength passes through the second light transmission part 134. The light of the LED element 112 adjacent to the LED element 112 emitting the light of the second wavelength passes through the first transmission part 124, and emits light of a third wavelength via the second light conversion sheet.SELECTED DRAWING: Figure 1 【課題】ユーザの選択による多様なカラー光をサポートするＬＥＤディスプレイ装置を提供する。【解決手段】本発明のＬＥＤディスプレイ装置１００は、第１波長の光を発生する複数のＬＥＤ素子１１２が行と列とに配置されたＬＥＤ基板１１０と、ＬＥＤ基板１１０の上部に位置してパンチングされた第１光透過部１２４が形成された第１光変換シート１２０と、第１光変換シート１２０の上部に位置してパンチングされた第２光透過部１３４が形成された第２光変換シート１３０と、を備える。複数のＬＥＤ素子１１２のうちの少なくとも１つのＬＥＤ素子の光は、第１光変換シート１２０を介して第２波長の光を発光させ、第２波長の光は第２光透過部１３４を通過し、第２波長の光を発光させるＬＥＤ素子１１２に隣接するＬＥＤ素子１１２の光は、第１透過部１２４を通過し、第２光変換シートを介して第３波長の光を発光させる。【選択図】図１
