Optical device

An optical device comprising:

• a drive circuit board;
• a first light-emitting element and a second light-emitting element mounted on the drive circuit board;
• a first insulating film covering the first light-emitting element and the second light-emitting element;
• a light-shielding layer disposed to overlap a gap between the first light-emitting element and the second light-emitting element on the first insulating film and including a first opening overlapping the first light-emitting element and a second opening overlapping the second light-emitting element;
• an overcoat layer covering the light-shielding layer;
• a plurality of first micro-lenses disposed on the overcoat layer and overlapping the first opening;
• and
• a plurality of second micro-lenses disposed on the overcoat layer and overlapping the second opening.
