The display device includes: an array substrate having an in-cell polarizing layer and a color layer; a counter substrate; a liquid crystal layer; a white light source; and a polarizing plate placed on the counter substrate on its one side opposite to a side on which the liquid crystal layer is provided. The color layer includes a red color layer, a green color layer and a blue color layer. The red color layer includes a red color filter and a red wavelength conversion layer which is located on its one side closer to the white light source than the red color filter. The green color layer includes a green color filter and a green wavelength conversion layer which is located on its one side closer to the white light source than the green color filter. The blue color layer includes a blue color filter.
