  • Electronic device
    Patent number: 9342174
    Abstract: The electronic device is an electronic device (100) having a multilayer structure including a touch panel (12) and a display device (10), the electronic device including a manipulation surface (22A) configured to accept an input from a user, the manipulation surface being provided on a surface closer to the touch panel, and constituting a curved surface such that a central portion of the manipulation surface (22A) is dented relative to an end of the manipulation surface (22A). The most-dented portion of the manipulation surface (22A) is dented relative to an end of the manipulation surface (22A) by a distance of not less than 0.2 mm and not more than 3.0 mm along a direction perpendicular to the panel plane.

  • Front light and method for producing same, reflective display device provided with front light, and electronic equipment provided with reflective display device
    Patent number: 9134475
    Abstract: A front light (1) includes a light source (8), a light guide plate (9), and a plurality of dots (4) that are provided on a surface of the light guide plate (9), which surface faces a light exit surface of the light guide plate (9). Each of the plurality of dots (4) includes (i) a light reflective layer (2) for reflecting light toward the light guide plate (9), and (ii) a dark layer (3) for absorbing light, the dark layer completely covering the light reflective layer (2) so as to be in contact with the light guide plate (9) without any gap between the light guide plate (9) and the dark layer (3).
