WIPO Patent Application WO/2021/079594
Kind Code:
A1
Abstract:
[Problem] To provide an illumination display device that has favorable light-guiding efficiency, saves space, and has a simple assembly process, and a method for manufacturing the same. [Solution] According to the present invention, an illumination display panel 1 that has display locations 1a where illumination display is possible and that forms a part of a housing comprises: a resin panel 2 having a first formation part 21 made of an opaque resin that is present except at the display locations 1a, and a second formation part 22 disposed on the rear surface of the first formation part and made of a light-transmissive resin having protrusions 22a at sections where the first formation part 21 is not present, the protrusions being fitted to the first formation part 21; and a light source mounting substrate 3 disposed on the rear surface side of the resin panel. At least light sources 31 of the light source mounting substrate 3 are sealed by the second formation part 22. An integrated molded article of the light source mounting substrate 3 and the second formation part 22 is filled at low pressure while compressing a cavity of a molding die and solidified.
