Interference filter and display device

A display device comprising:

• an interference filter including:
• a base body including a major surface;
• a lower semi-transmissive layer provided on the major surface;
• and
• an upper semi-transmissive layer provided on the lower semi-transmissive layer,
• the base body, the lower semi-transmissive layer, and the upper semi-transmissive layer forming a first region to selectively transmit blue light, a second region to selectively transmit green light, and a third region to selectively transmit red light, the first region, the second region and the third region being arranged in a plane parallel to the major surface, and
• a distance between the lower semi-transmissive layer and the upper semi-transmissive layer in the second region being shorter than a distance between the lower semi-transmissive layer and the upper semi-transmissive layer in the first region, and shorter than a distance between the lower semi-transmissive layer and the upper semi-transmissive layer in the third region;
• a wavelength selective absorption layer stacked with the base body;
• and
• a light control layer stacked with the base body,
• the wavelength selective absorption layer including:
• a blue first absorption layer including a portion overlapping the first region as viewed along a first direction perpendicular to the major surface;
• a green second absorption layer including a portion overlapping the second region as viewed along the first direction;
• and
• a red third absorption layer including a portion overlapping the third region as viewed along the first direction, and
• the light control layer controlling an intensity of a light passing through each of the first region, the second region, and the third region.
