BUILDING MATERIAL WITH DISPLAY DEVICE, AND DISPLAY DEVICE

摘要

A building material in which an image can be displayed on a transparent plate such as a windowpane is realized using a configuration that is simple and low-cost. A window member (5) includes a display panel (11) having a display region (11a) that can switch between a light transmitting state and a non-light-transmitting state and a frame region (11b) serving as a non-display region formed on an outer side of the display region (11a), a light-transmitting cover (40) disposed on the display panel so as to cover at least a part of the frame region (11b) and at least a part of the display region (11a) that is adjacent to the frame region (11b), and a pair of windowpanes (3, 3) that are held in parallel in the window frame (2). The light-transmitting cover (40) is shaped such that the thickness thereof decreases from the display region (11a) toward the frame region (11b).
