DISPLAY DEVICE AND COMPOSITE DISPLAY DEVICE

摘要

A display device which can be driven by a thin-film transistor and has a high brightness is provided. A low-voltage-driven inorganic luminescent layer 121 and a control transistor 105 are formed on a substrate 111. The voltage which is applied to the inorganic luminescent layer 121 is controlled by the control transistor 105. The inorganic luminescent layer 121 has such strength against heat and any damage such that the inorganic luminescent layer 121 can be formed by sputtering method. A top-emission type display device and a bottom-emission type display device can be formed on the same substrate and the luminescent light can be emitted from the same position.
