Abstract
An optical module of the present disclosure includes a first panel including a first light-emitting element, a first power supply wiring and a second power supply wiring; a second panel including a second light-emitting element having light emission luminance per unit current lower than that of the first light-emitting element, a third power supply wiring and a fourth power supply wiring; and a prism configured to synthesize first image light emitted from the first panel and second image light emitted from the second panel. A first potential difference is smaller than a second potential difference, the first potential difference being a difference between a potential applied to the first power supply wiring and a potential applied to the second power supply wiring, the second potential difference being a difference between a potential applied to the third power supply wiring and a potential applied to the fourth power supply wiring.
