Abstract: Performance of an electronic apparatus is improved. A terminal of the electronic apparatus includes: a first metal layer made of aluminum; and a second metal layer which is arranged on the first metal layer, which is bonded to a cap film and which is made of titanium. The cap film includes a metal film which is made of titanium and is bonded to the second metal layer. The metal film includes: a contact portion which totally covers a portion of the metal layer ML3 of the terminal, the portion being exposed at an opening of an insulating layer from the insulating layer; and a peripheral portion which is arranged outside the opening and which continuously surrounds the contact portion in plan view. The insulating layer intervenes between the peripheral portion of the metal film and the terminal.

Abstract: A display device includes: a light source device including a first light source, a second light source, and a third light source; a display; a storage configured to store data indicating a lighting pattern of the light source device; a controller configured to control the lighting pattern based on the input data and the data. The controller is configured to produce n lighting periods during a display output period of a frame image. Colors of light from the light source device during the n lighting periods differ from one another. The data includes information indicating lighting patterns that allow different color gamuts to be reproduced in the n lighting periods. The controller is configured to control, when the color reproduction changes, the lighting pattern based on a difference between the lighting pattern for the input data before the change and the lighting pattern for the input data after the change.
