发明名称 DISPLAY DEVICE
摘要 <P>PROBLEM TO BE SOLVED: To provide a display device capable of radiating light in plural different directions and obtaining even illumination light using the same point light source or point light source group. <P>SOLUTION: A display device 10 comprises: a point light source 15 having high directivity; a casing 13 having a bottom plate part and a side plate part on which the point light source 15 is mounted, and having a light conducting reflection plate 14 at an opening thereof; a housing 11 which receives the casing 13, has a bottom face part and a side face part, and has a light-transmissive display plate 12 provided at the opening. The light conducting reflection plate 14 is formed such that the light transmittance is higher and the light reflectance is lower away from the point light source 15. The display device 10 has a light direction adjusting plate 16 that is provided between the point light source 15 and the light conducting reflection plate 14 so as to cover the point light source 15 by being erected from the bottom plate part. The light direction adjusting plate 16 is provided with at least one light direction adjusting hole 17 formed about optical axes other than the optical axis of the point light source. <P>COPYRIGHT: (C)2013,JPO&INPIT
