It incorporates a drive substrate 3 on which 24 elements 2 are mounted in a matrix. Then, in the gap between the drive substrate 3 and the frame body 1, a non-fluidic silicone resin 4 is sealed as shown by the diagonal lines in FIGS. In particular, the silicone resin 4 has an advantage that the stitching process can be simplified by using a one-component quick-curing resin.

As described above, the LE according to the present invention
In the D display device and the manufacturing method thereof, since the gap between the frame and the drive substrate is sealed with the non-fluidic silicon resin and the drive substrate is filled with the fluidized silicon resin, the non-fluidic silicone resin is It does not spill out from the gap and can be cured quickly, which is very convenient for work. In addition, since fluid silicon resin is used to waterproof the drive board,
The resin thoroughly penetrates into the drive substrate and the element, and the resin does not flow out from the non-fluidic silicone resin. Further, since the same silicone resin is used, the reliability as a whole is high.

Furthermore, since a resin is used instead of the conventional molded product, the degree of freedom in the shape and structure of the drive substrate and the frame is increased, and the size of the device can be increased. Further, since only the resin is cast, the process is simple, the molding cost is unnecessary, and the cost of the entire apparatus can be reduced.
