1. A display device comprising:
- a first light-transmitting substrate and a second light-transmitting substrate which are disposed to face each other;
a display element sandwiched between the first light-transmitting substrate and the second light-transmitting substrate; and
a layer including stacked polarizers provided between a viewer and the first light-transmitting substrate;
wherein the stacked polarizers are arranged to so that their absorption axes are deviated from a parallel Nicols state.

Abstract
To provide a display device having a high contrast ratio by a simple and easy method and to manufacture a high-performance display device at low cost, in a display device having a display element between a pair of light-transmitting substrates, layers each including a polarizer having different wavelength distribution of extinction coefficient from each other with respect to the absorption axes are stacked and provided on an outer side of the light-transmitting substrates. Further, a retardation plate may be provided between the stacked polarizers.
