In the display device, since each unit of a large number of LEDs 3 mounted in an inverted triangular arrangement on the front surface 2a of the LED cell 2 is inserted into the large and rectangular opening 5 of the front cover 4, each opening is formed. The space around the LED 3 in the portion 5 was large, and the front surface 2 a of the LED cell 2 was exposed in the opening 5. Then, in order to protect the leads 3a of the large number of LEDs 3 against static electricity and rainwater from the outside, the front surface 2a of the LED cells 2 is usually potted with a resin layer 8 such as silicon resin or urethane resin. That is, irregular reflection of light easily occurs on the front surface 2a. On the other hand, since the overhang dimension A of the louver 6 is restricted due to the inverse proportion to the viewing angle θ, the incidence of the external light SL1 at all incident angles cannot be restricted.
When the incident angle of the external light SL1 becomes shallow, a part of the external light SL2 whose incident angle becomes shallow passes through the opening 5 and is irregularly reflected by the front surface 2a of the LED cell 2, and the irregularly reflected light TL Because of the spectator's eyes, a large number of LEDs 3 have black floating due to diffuse reflection of external light, and LED 3
Has a problem that the sharpness of color images and / or color characters is lost.

Must be set with high precision. However, conventional LED
In the display device, one unit of a large number of LEDs 3 mounted in an inverted triangular shape on the front surface 2a of the LED cell 2 is inserted in a very loose state having play in the large, square opening 5 of the front cover 4. Therefore, the inclination of the optical axis P of the LED 3 inserted into the opening 5 and the variation of the adjacent distance L frequently occur. This is the front surface 2 of the LED cell 2
a) The LED 3 is assembled to the front cover 4 without correcting the inclination of the optical axis P and the variation of the adjacent distance L generated in the process of mounting a large number of LEDs 3 and the transporting process after the mounting. This is because the LED 3 interferes with the front cover 4 at the time of assembly, and the inclination of the optical axis P and the variation of the adjacent distance L are likely to occur. Then, the LED due to the variation of the inclination and the interval of the optical axis P of the LED 3 as described above.
The shift of the optical axis P of No. 3 is caused by uneven brightness and uniformity (Unif
