Abstract:
According to an embodiment, an electronic device, comprises a transparent member, an optical sensor disposed under the transparent member and including a light transmitter configured to emit light of a designated wavelength band and a light receiver configured to obtain light of the designated wavelength band emitted from the light transmitter and reflected by an external object adjacent to the transparent member, a first optical filter disposed between the transparent member and the optical sensor, having a first transmittance for light of the designated wavelength band, and configured to reflect light outside the designated wavelength band, and a second optical filter disposed between the transparent member and the first optical filter, having a second transmittance less than the first transmittance for light of the designated wavelength band, and configured to absorb at least a portion of the light reflected by the first optical filter.
