Patent abstract
The invention provides a display device of which a contrast ratio is enhanced. By providing stacked polarizing plates so as to be in a cross nicol state, a contrast ratio of a display device can be enhanced. The stacked polarizing plates are stacked outside a light-transmissive insulating substrate in a parallel nicol state. When the number of polarizing plates is four or five in total, a contrast ratio becomes the highest.
