PROBLEM TO BE SOLVED: To provide an LED display device capable of easily taking the balance of mixed colors while reducing a manufacturing cost due to the reduction of the number of the pieces to be used of costly blue and green LED light emitting elements in an LED display device which performs display in full colors by using three colors red, blue and green. SOLUTION: The arrangement of the LED light emitting elements of the LED display device is configured by arranging the four LED light emitting elements; the red LED light emitting elements 30r, 31r, 32r, 33r of the first LED light emitting element at four corners within a reference section 25, arranging the green LED light emitting elements 30g of the second LED light emitting element at the center on the diagonal lines of the reference section 25, and arranging the blue LED light emitting elements 30b, 31b of the third LED light emitting element at the centers on the sides in the vertical direction 39 of the reference section 25.
