ｄｉ とｄ２を定める。Place the transmission scattering plate l on the top, and place an appropriate distance d below it.
A large display panel 2 is placed at a distance 1, and an enlarged point light source is placed below it at an appropriate distance d2. The large display panel 2 is constructed by connecting a plurality of transmissive type Leysten nematic liquid crystal display units 10. Each display unit 10 consists of a transparent liquid crystal portion 11 and an opaque frame portion 12. Therefore, the frame portion 12 of the display unit 10 and the seam portion between each display unit 10 are opaque and do not transmit light. A drive section (not shown) of the liquid crystal display unit 10 is arranged in the frame portion 12. The enlarged point light source 3 is provided in such a connected large display panel 2 in order to eliminate the opaque portion during actual display. This enlarged point light source 3
is the liquid crystal part 1 which is the display surface for each display unit.
1 below the center. By providing the enlarged point light source 3 in this manner, the light from the enlarged point light source 3 is transmitted through the liquid crystal section 11, and the liquid crystal section 11 is enlarged and projected onto the transmission scattering plate 1. Frame portion 12 of display unit 10
The dark areas caused by the connecting portions are eliminated by the scattering effect of the transmission scattering plate 1. That is, by creating the scattering portion shown by the hatched area 22 in FIG. 2, the amount of light transmitted is averaged out to be approximately uniform throughout the entire structure. The positional relationship between the transmissive scattering plate 1 and the enlarged black light #3 with respect to the large display panel 2 is such that they are adjacent to each other on the transmissive scattering plate 1 on which the liquid crystal portion 11, which is the display surface portion of each display unit 10, is projected. Therefore, the intervals di and d2 are determined.

As a result, there are no gaps in the image, resulting in an extremely easy-to-read display.
