Abstract
A detection device includes a photodetector, a filter layer overlapped on the photodetector and including a first color material having a peak transmittance for light in a first wavelength band, and a display panel arranged over the filter layer, wherein the filter layer has a peak transmittance of 90% or more, a transmittance of 80% or more at a wavelength of 550 nm, a transmittance of 10% is more at a wavelength of 600 nm, and a transmittance of 10% or less at a wavelength of 680 nm to 700 nm.
Claims7
A detection device comprising:
- a photodetector;
- a filter layer overlapping the photodetector and including a first color material having a peak transmittance for light in a first wavelength band;
- and
- a display panel arranged over the filter layer,
- a micro lens on a light receiving side on the photodetector;
- a first light shielding layer arranged between the photodetector and the filter layer, being in direct contact with the filter layer, and including a first opening overlapping the photodetector;
- and
- a second light shielding layer arranged between the photodetector and the micro lens, and including a second opening overlapping the photodetector and the first opening,
- wherein the filter layer has a peak transmittance of 90% or more,
- a transmittance of 80% or more at a wavelength of 550 nm,
- a transmittance of 10% or more at a wavelength of 600 nm, and
- a transmittance of 10% or less at a wavelength of 680 nm to 700 nm
- the first light shielding layer and the second light shielding layer are formed of a metal material, and
- the filter layer is arranged between the photodetector and the micro lens.
