Abstract: A display device with both light-emitting and reflective display capabilities is disclosed. This device includes first and second electrodes provided on a first substrate, a second substrate provided to be spaced apart from and oppose the first substrate, a third electrode provided on the second substrate, a first layer which is provided between the first and second substrates on the first substrate side and which contains a light emissive material that emits light through electrochemical oxidation or reduction, a second layer which is provided between the first and second substrates on the second substrate side and which includes a coloring material that changes in color due to electrochemical oxidation or reduction, and a third layer between the first and second layers. The third layer is an electrolytic layer having non-transmissivity or transmission retardancy against the light emissive material or its oxidation or reduction species.

Abstract: In a light emitting device, a first distance between the first substrate and the second substrate in an area where a luminescent material and a sealant are separate from each other is larger than a second distance between the first substrate and the second substrate in a clearance where the luminescent material is filled, and a third distance in the area between the luminescent material and the sealant is larger than the second distance.
