Abstract
Provided is a display device having high visibility regardless of the intensity of external light. Provided is a display device capable of a variety of display. Provided is a display device that can operate with low power consumption. The display device includes a first electrode, a second electrode, a first liquid crystal layer, a second liquid crystal layer, a first coloring layer, and a first insulating layer. The first liquid crystal layer overlaps with the second liquid crystal layer with the first insulating layer therebetween. The first electrode is configured to reflect visible light. The second electrode includes a portion not overlapping with the first electrode and is configured to transmit visible light. The second liquid crystal layer includes a first portion overlapping with the first coloring layer and the second electrode, and a second portion not overlapping with the first coloring layer. The first portion contains monomers and liquid crystal. The second portion contains a polymer obtained by polymerization of the monomers.
