DISPLAY DEVICE
First Claim
1. A display device comprising:
- a first light-transmitting substrate and a second light-transmitting substrate arranged to face each other;
a display element disposed between the first light-transmitting substrate and the second light-transmitting substrate;
a first layer including first stacked polarizers adjacent to the first light-transmitting substrate; and
a second layer including second stacked polarizers adjacent to the second light-transmitting substrate,wherein the first light-transmitting substrate and the second light-transmitting substrate are disposed between the first layer and the second layer,wherein transmission axes of the first stacked polarizers are arranged in a parallel nicol state,wherein transmission axes of the second stacked polarizers are arranged in a parallel nicol state, andwherein the transmission axes of the first stacked polarizers and the transmission axes of the second stacked polarizers are arranged in a cross nicol state with a deviation.

Abstract
An object is to provide a display device with high contrast ratio. Another object is to manufacture such a high-performance display device at low cost. In a display device having a display element interposed between a pair of light-transmitting substrates, a stack of polarizer-including layers in a parallel nicol state is provided outside each of the light-transmitting substrates. Here, transmission axes of polarizers that are stacked in the stack on one side of the display element and transmission axes of polarizers that are stacked in the stack on another side of the display element are arranged to be displaced from a cross nicol state. Also, a retardation film may be provided between the polarizers that are stacked and the substrate.
