PROBLEM TO BE SOLVED: To improve performance property of a performance display device of a game machine. SOLUTION: This performance display device 40 illuminates a light from a light emitting means to a half mirror 42 having a filter layer transmitting a part of an incident light and reflecting the rest to execute a prescribed performance with the light transmitting through the half mirror 42. The back side of the filter layer in the half mirror 42 is superposed with translucent diffusion layers diffusing the light illuminated from the back side, and the outer circumferential edges of the half mirror 42 are retained with a first retaining member 50. An inner area surrounded with the half mirror 42, the first retaining member 50 and a performance board 60 is erected with a beam part 58 separated from the half mirror 42. The internal circumferential face 50a of the first retaining member 50 facing between the half mirror 42 and the performance board 60, and the beam part 58 are treated with a process improving reflectivity of the light illuminated from the light emitting means 62.
