Abstract: A light adjustment device includes a plurality of liquid crystal cells each including a light adjustment region that polarizes light emitted from a light source, the liquid crystal cells being stacked in a direction in which the light is emitted. The liquid crystal cells each include a first substrate in which a plurality of first metal wires are provided, and a second substrate in which a plurality of second metal wires are provided and that sandwiches a liquid crystal layer with the first substrate.

Abstract: According to an aspect, a display device includes: a substrate including a display region and a non-display region surrounding the display region; at least one driver IC including connecting terminals with a first surface fixed to face the non-display region; first wires supplying a signal to the display region; first bumps connected with the first wires; second wires transferring a signal to and from outside; second bumps connected with the second wires; and inspection wires. The connecting terminals of the driver IC include first connecting terminals overlapping the first or second bumps in plan view, and a second connecting terminal not overlapping the first or second bumps in plan view. At least one inspection wire includes a connecting conductor between itself and the second connecting terminal, and at least one fuse portion, a narrower width part of the inspection wire in plan view.

Abstract: A light adjustment device in which a plurality of liquid crystal cells each including a light adjustment region configured to polarize light emitted from a light source are stacked in a direction in which the light is emitted is disclosed. The liquid crystal cells each include a first substrate including a plurality of first drive electrodes extending in a first direction in the light adjustment region, and a second substrate sandwiching a liquid crystal layer between the first substrate and the second substrate and including a plurality of second drive electrodes extending in a second direction different from the first direction in the light adjustment region.
