PROBLEM TO BE SOLVED: To provide a display device for measuring instruments that can prevent reflected glare from a light guide body projecting from the rear side of a display board to the front side and thereby enhance display quality.SOLUTION: A display device for measuring instruments 1 is equipped with a light source 10, a display board 20 having an indicator part 21 for displaying measured quantities, an end leaf member 30 surrounding the display board 20, and a light guide body 40 having a light receiving part 41 disposed on the rear side of the display board 20 to receive light from the light source 10 and a convex part 42 projecting from the rear side of the display board 20 to the front side to emit light according to the light received by the light receiving part 41. The light guide body 40 is equipped with a light diffusing unit 43 that diffuses light leaking from the convex part 42 to the end leaf member 30 on the optical path between the light receiving part 41 and the end leaf member 30.SELECTED DRAWING: Figure 5
【課題】表示板の裏側から表側に突き出した導光体からの映り込みを防止して表示品位を向上することができる計器用表示装置を提供する。【解決手段】計器用表示装置1は、光源10と、計測量を表示する指標部21を有する表示板20と、表示板20を囲む見返し部材30と、表示板20の裏側に設けられ、光源10からの光を受光する受光部41と、表示板20の裏側から表側に突き出して受光部41が受けた光に基づき発光される凸状部42と、を有する導光体40と、を備える計器用表示装置1であって、導光体40は、受光部41と見返し部材30との光路中に、凸状部42から見返し部材30に向かって漏れる光を拡散させる光拡散部43を備えている。【選択図】図5
