Provided is a display device with which it is possible to realize an indoor environment comfortable to a user. The display device is provided with a frame member and a flexible display. The frame member is disposed around a daylighting section of a structure including the daylighting section for transmitting light, and includes a wind-up unit including a rotating shaft. The flexible display includes a dimming layer and a display element layer which is disposed on the dimming layer and which includes a light emitting layer. The flexible display can be wound up by rotating the rotating shaft included in the wind-up unit of the frame member, and can be pulled out of the wind-up unit. L'invention concerne un dispositif d'affichage permettant d'obtenir un environnement d'intérieur confortable pour un utilisateur. Le dispositif d'affichage est pourvu d'un élément de cadre et d'un écran flexible. L'élément de cadre est disposé autour d'une section d'éclairage naturel d'une structure comprenant la section d'éclairage naturel destinée à émettre de la lumière, et comprend une unité d'enroulement pourvue d'un arbre rotatif. L'écran flexible comprend une couche de gradation ainsi qu'une couche d'élément d'affichage disposée sur la couche de gradation et qui présente une couche électroluminescente. L'écran flexible peut être enroulé par rotation de l'arbre rotatif présent dans l'unité d'enroulement de l'élément de cadre, et peut être retiré de l'unité d'enroulement. 使用者にとって快適な屋内環境を実現可能な表示装置を提供する。この表示装置は、フレーム部材と、フレキシブルディスプレイとを備える。フレーム部材は、光を透過する採光部を有する構造物のうちの採光部の周囲に設置され、回転軸を含む巻き取り部を有する。フレキシブルディスプレイは、調光層と、その調光層の上に設けられた発光層を含む表示素子層とを有し、フレーム部材の巻き取り部に設けられた回転軸の回転により巻取り可能であると共に巻き取り部から引き出し可能である。
