Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an LED display lamp capable of reducing the number of LEDs while securing visibility by efficiently using the light from the LEDs. SOLUTION: In this display lamp 2, the front surface 2c of a flat non-display portion 2a is surrounded by a bucket-like globe 5 serving as a display portion 2b, and light sources 4 are housed inside. The light sources 4 are fixed to a case 3 via a base board 6, and includes a pair of end LEDs 42, 43 disposed at both sides with the center in a lateral direction held therebetween. Each of the LEDs diagonally emits light toward a region of the globe 5 at an increased area irradiated with the light. As a result, it is possible to reduce the number of LEDs required for the display lamp 2. Moreover, the center 51 of the globe 5, at which the light is liable to run short, is sufficiently irradiated with the light by a center LED 41 or a reflector, thereby securing visibility. Consequently, the light can be oriented forward by the reflector, thus achieving the effective use of the light.
