Display device and vehicle display device

Abstract

A display device includes a circuit board, a first light-emitting element, a first conductive wire, and a second conductive wire. The first light-emitting element is located on the circuit board and includes a first electrode and a second electrode. The first conductive wire surrounds the first light-emitting element, and the second conductive wire surrounds the first conductive wire, wherein the electric field strength between the first conductive wire and the second conductive wire is greater than or equal to the electric field strength between the first electrode and the second electrode of the first light-emitting element. An automotive display device is also provided.
