摘要:
An object of the present invention is to provide a display device having a high contrast ratio by a simple and easy method. Another object of the present invention is to manufacture such a display device having a high contrast ratio at low cost. The present invention relates to a display device including a first substrate; a second substrate; a layer including a display element, wherein the layer including the display element is interposed between the first substrate and the second substrate; and stacked polarizers on the outer side of the first substrate or the second substrate. The stacked polarizers are arranged to be in a parallel Nicols state and the wavelength distributions of the extinction coefficients of the stacked polarizers are different from each other.
