Title: DISPLAY DEVICE, VEHICLE, ELECTRONIC SIGN, AND PORTABLE ELECTRONIC DEVICE
Abstract:
Provided is a display device (100) equipped with a touch screen (1) provided with a display surface (10) which displays an image, and which receives touch inputs from a user. The display surface (10) is curved along a direction extending from a first end (11a) at a periphery (11) of the display surface (10), towards a second end (11b) located at the periphery (11) at a side opposite to the first end (11a), with a centre (C) of gravity of the surface area of the display surface (10) therebetween. The display surface (10) is provided with: a first display area (10a) which has a constant curvature along the direction extending from the first end (11a) towards the second end (11b), which includes the first end (11a), and which does not include an inflection point; and a second display area (10b) which continues on from a second-end (11b) side of the first display area (10a), which has a constant curvature, and which does not include an inflection point. The first display area (10a) and the second display area (10b) satisfy a first condition and/or a second condition. The first condition prescribes that one from among the first and second display areas (10a, 10b) have a concave surface, and the other have a convex surface. The second condition prescribes that the curvatures thereof be mutually different.
