Abstract

The present disclosure provides an electronic device and a manufacturing method for the electronic device. The electronic device includes a light permeable display screen, a light permeable cover plate and one or a plurality of light sensors. The light permeable display screen includes a first surface and a second surface opposite to the first surface. The light permeable cover plate faces the first surface, covers the light permeable display screen, and includes a flat plate portion and one or a plurality of curved surface portions. The one or the plurality of curved surface portions extends away from the flat plate portion, protrudes from the light permeable display screen horizontally, and bends towards the light permeable display screen vertically, so as to form one or a plurality of accommodating spaces together with the light permeable display screen. The light sensor is arranged in the accommodating space.
