Abstract:

Disclosed is a pointer-type display device having a high degree of design freedom, with which a design can be efficiently illuminated. Said device is provided with a light guide letter board (10), a light guide body (20), and a pointer (30), and a first light source (51). The light guide letter board (10) comprises: a transparent light guide section (11) having a letter plate hole section (111) through which a pointer shaft (41) is inserted; a design display section (12) that displays a design and is formed on the front face of the light guide section (11); a first optically transparent emission section (122a) of the design display section (12) that emits light; and an optical diffusion section (13) provided in a position corresponding to this first optically transparent emission section (122a). Light is emitted from the first optically transparent emission section (122a) by means of light-diffusion that is achieved by this optical diffusion section (13). The light guide body (20) causes light to be introduced from the first light source (51) into an inside wall light-introduction section (111a) that is arranged in the inside wall of the letter plate hole section (111).
