The article according to the present design is a display unit using a fine LED element as a
light source. Although it can function alone, it is usually used by assembling a plurality of them. By combining many of them, a
large screen can be obtained, and it is also possible to construct a relatively small screen with a small number of units. The article of the present application has a layer (hereinafter referred to as "decoration layer") with various graphical decorations such as photographs, paintings, etc. applied so as to be visually recognized on its screen, and slightly opens around the LED element serving as a
light source. Therefore, as shown in the reference diagram showing an example of the embodiment, when the article of the present application is not energized, only the decoration on the decoration layer is visually recognized, and when it is energized, only the video projected on the display is visually recognized (in the reference enlarged view of the C-C part, the part indicated by the lead wire 1 is the opening, 2 is the display surface, 3 is the LED element, and 4 is the surface of the decoration layer). In this way, the article of the present application functions as a
display device for displaying videos, etc., and also functions as a decorative material used by being embedded in the inner and outer walls of buildings, etc. Although there are various specific usage scenarios, for example, if it is used on the inner wall of the
living room of a house, it can be used as a display for watching television broadcasts, etc. On the other hand, when not watching, it becomes a wall as it is, so there is no need to place a television
receiver in the
living room, and the degree of freedom in the configuration of the
living space increases.
