<p>A plurality of light-emitting diode elements (8) are disposed in a generally cylindrical outer frame (3) of an indicator main body (1). Recesses (4,5,6) are formed on the outer surface of the outer frame (3) so as to be arranged in its circumferential and longitudinal directions. Several ribs (19a,19b,19c) are formed on the inner surface of a hood (2) so as to be arranged in its circumferential direction. The ribs (19a,19b,19c) of the hood (2) are fitted in selected ones of the recesses (4,5,6) of the outer frame (3) to form an indicator (50). A display panel is constituted by two-dimensionally arranging a large number of the above indicators (50) on a base (51). <IMAGE></p> |
