Abstract

An LED display device having an LED array for a meter on a printed circuit board. A diffusing radiation lens array is disposed facing the LED array. A cover lens is overlapped on the lens array. The cover lens transmits LED light which passed through the lens array. The cover lens has at least a scale mark, a character and a sign. A sheet is interposed between the lens array and the cover lens. The sheet limits radiation of predetermined diffused light from the lens array while partially transmitting the diffused light. The cover lens has a scale mark dent and a character dent formed on its rear interior surface, and displays the scale mark and character by means of an LED light from another LED array.
