Abstract
A large‐capacity, dot, TFEL display panel with a density of 4.2 lines/mm is fabricated by employing a stacked insulator structure. Improvement of the breakdown phenomenon, from propagation to self‐healing mode, by interposing a self‐healing type insulator between the metal electrode and the second insulator is discussed in this paper. Emission efficiency and luminance are 1.6 and 1.8 times higher, respectively, than with conventional TFEL devices. This is accomplished by application of a low‐resistivity film adjacent to the emitter.Keywords
