1. A display device, comprising:
a first insulating substrate;
a second insulating substrate opposed to the first insulating substrate;
a first pixel electrode and a second pixel electrode arranged between the first insulating substrate and the second insulating substrate;
a wavelength conversion element located between the first pixel electrode and the first insulating substrate or between the first pixel electrode and the second insulating substrate, to convert light of a first wavelength polarized in a first polarization direction into light of a second wavelength polarized in a second polarization direction; and
a liquid crystal layer located between the first insulating substrate and the second insulating substrate, having a first thickness in an area opposed to the first pixel electrode, and having a second thickness greater than the first thickness in an area opposed to the second pixel electrode,
wherein the second polarization direction is perpendicular to the first polarization direction.
