no. 1 Embodiment approach
[0067] figure 1 It is a figure explaining the video display system 1 of this embodiment. figure 1 (a) is a perspective view of an image display system 1 including a reflective screen 10, figure 1 (b) is a side view of the video display system 1 including the reflective screen 10 . The video display system 1 includes a reflective screen unit 5 having a reflective screen 10 and a video source LS. In the video display system 1 of the present embodiment, the reflective screen 10 reflects the video light L projected from the video source LS, and displays a video on the screen. This video display system 1 can be used, for example, as a front projection television system or the like in which video light L is projected from a video source LS.
[0068] The image source LS is an image light projection device that projects the image light L to the reflective screen 10 . As the image source LS, for example, a general-purpose short-focus projector can be used. In the state of use, whe...
no. 2 Embodiment approach
[0121] Next, a second embodiment of the present invention will be described. In the following description, duplicative descriptions of parts that perform the same functions as those of the first embodiment are appropriately omitted, and the same reference numerals are attached or the same reference numerals are appended at the end.
[0122] The reflective screen of the second embodiment has the same layer structure as the reflective screen of the first embodiment, but differs from the first embodiment in that the paint forming the reflective layer further contains a dark-colored material.
[0123] The paint forming the reflective layer 20 is composed of a scaly metal film (metal flake) 25, a binder, a drying aid, a control agent, a dark-colored material, and the like. It should be noted that the above-mentioned scaly metal thin film 25 constituting the paint, the binder, the drying aid, and the control agent are the same as those of the above-mentioned first embodiment.

no. 3 Embodiment approach
[0143] Next, the main reference Figure 10 ~ Figure 17 A third embodiment of the present invention will be described. In this embodiment, the reflective screen 110, the screen frame 102, the image display system 101, etc., which are the main parts of this embodiment, are described and illustrated according to the needs of explanation, and are often installed as necessary in actual products. A leg portion holding the screen housing 102 on the floor 105, a joint portion holding the screen housing 102 on a wall or the like, or the like.
[0144] In this embodiment, for the sake of convenience, the X-axis direction shown in the figure is called the left-right direction (especially the direction of the arrow is right), and the Y-axis direction is called up and down (especially the direction of the arrow is up), The Z-axis direction is referred to as front and rear (in particular, the direction of the arrow is referred to as front). Taking the platform as a reference, the directio...
