Zusammenfassung:PURPOSE:To provide the LED display unit which is easily looked up at even from below while green with low luminance and is easily viewed even outdoors. CONSTITUTION:The LED display unit has one dot of its checkered light emission surface composed of a red LED 2b and a green LED 2a, low-luminance green is arranged closely to the side of a hood 4, whose top surface is tapered to secure upward visibility. Consequently, red LEDs 2a are hardly affected by the sunshine on the side of the hood 4, so the visibility is good even in the daytime and the upward visibility is also improved.
