Description

Technical field

[0001] The present invention relates to a light emitting device, and in particular to an electroluminescent device. Background technique

[0002] The electroluminescent device is a self-luminous (Emissive) device. Because the electroluminescent device has no viewing angle limitation, low manufacturing cost, high response speed (approximately more than a hundred times that of liquid crystal), power saving, DC drive that can be used in portable machines, large operating temperature range, light weight and easy Miniaturization and thinning of hardware equipment, etc. Therefore, electroluminescent devices have great development potential and are expected to become the next generation of novel flat-panel displays.

[0003] Generally speaking, an electroluminescent device is composed of an upper electrode layer, a lower electrode layer, and a light-emitting layer sandwiched between the two electrode layers. The lower electrode layer is generally made of transparent cond...
