ABSTRACT:
An electroluminescent device includes one or more electroluminescent laminates attached onto a bottom surface of a base panel and one or more patterns attached onto an upper surface of the base panel. The patterns each may include two or more spaces having different material of different brightnesses to generate light of different brightness through the different materials when the electroluminescent laminate is energized. The patterns may include one or more outer peripheral spaces formed around the other inner peripheral surfaces, to generate light of different brightnesses.
