For example, when the red and green light-emitting diodes 42 and 43 are turned on to display orange, the red and green light-emitting regions 47 and 48 are eccentric with respect to the center of the mounting surface 44. Eccentric in the horizontal direction 49. However, when a person looks at the device,
The viewing direction is easily performed along the horizontal direction 49. This is because humans need to stretch and squat down to see the device vertically. When a person observes the device, the user observes the light emitting diode lamp 41 along the horizontal direction 49 in order from left, center, and right to green, orange, and red.

である。Next, since the blue light emitting diode 45 has low luminous efficiency, it is fixed on the submount 50 via a silver paste so that the Pn junction is located below (junction down) in order to increase the luminous efficiency. . However, since the silver paste has good wettability and covers even the Pn junction, current leakage occurs. Therefore, the present invention has been made in view of the above-mentioned conventional drawbacks, and provides a light emitting diode display device having good display quality at the time of color mixing and having no current leakage.
