1. An electronic device comprising:
a first display panel including a first display surface; and
a second display panel including a second display surface and configured to be disposed such that light emitted from the first display surface is incident on the second display surface,
wherein the first display panel is configured such that the light emitted from the first display surface and incident on the second display surface includes a large amount of P-polarization components,
the second display panel is a reflection-type display panel, and further includes a polarizer disposed on the second display surface and configured to absorb S-polarization components of incident light,
the first display panel is a transmission-type display panel,
the first display panel further includes a liquid crystal element layer, a first polarizer having an absorption axis parallel to a horizontal direction of the first display surface, a second polarizer having an absorption axis in a direction of absorbing a polarization component in a perpendicular direction of the first display surface, and a backlight,
the first polarizer and the second polarizer face each other with the liquid crystal element layer interposed therebetween,
the first display panel is further configured to display in a normally black mode, and
the second polarizer has an absorption axis inclined downward in the perpendicular direction of the first display surface from a normal direction of the first display surface.
