To provide a transparency control display capable of controlling visual transparency in a viewer on a display surface and also capable of maintaining the transparency from a display rear surface, a home door with transparency control display, and a transparency control display for vehicle.SOLUTION: There is provided a transparency control display in which a pixel display part having LED and a control circuit that controls emission of the LED is arrayed on a base substrate having optical transparency in a horizontal direction and a vertical direction, the entire surface of the display is configured such that transparency on the surface disappears by controlling light emitting luminescence of LED when LED lights up, and the entire rear surface of the display is configured to have transparency visually when LED lights up and when LED lights out. The pixel display part may provide a diffusion lens having diffusing properties on the surface of LED.SELECTED DRAWING: Figure 9

    【課題】ディスプレイ表面の観視者における視覚的な透過性を制御でき、かつ、ディスプレイ裏面からの透過性を維持することのできる透過性制御ディスプレイ、透過性制御ディスプレイ付ホームドア及び車両用透過性制御ディスプレイを提供する。【解決手段】光透過性を有するベース基材上に、LEDとその発光を制御する制御回路とを有するピクセル表示部が、水平方向と垂直方向に配列されたディスプレイにおいて、ディスプレイの表面全体は、LEDの点灯時に、LEDの発光輝度を制御することにより、表面の透過性が消失し、ディスプレイの裏面全体は、LEDの点灯時及び消灯時の何れにおいても、視覚的に透過性を有する。ピクセル表示部には、LEDの表面に、拡散性を有する拡散レンズが設けられたことでもよい。【選択図】図9
