Zusammenfassung: | There is provided a light-emitting-device-integrated building material having a simple structure that can be manufactured at a relatively low cost, and having high design flexibility. The light-emitting-device-integrated building material includes a decorative member having at least part of an outer surface to form an external surface of a structure, and two or more surface emitting panels, and an inter-panel non-light emitting region is formed between a light emitting surface of one surface emitting panel and a light emitting surface of another surface emitting panel. In addition, a relation between the inter-panel non-light emitting region and a projection plane overlapping region positioned outside the inter-panel non-light emitting region in an outer surface of the decorative member satisfies the following condition (1).
(1) When an average value of luminance per unit area of the inter-panel non-light emitting region in a front view is indicated as A1, and an average value of luminance per unit area of the projection plane overlapping region is indicated as A2, a value of X1 in the following expression (A) is 55 or more and 3000 or less. X 1 = A 2 / A 1 100 100 |
