Title:
電界放出光源素子及びその製造方法
Document Type and Number:
Japanese Patent JP5649734
Kind Code:
B2
Abstract:
A field emission light source device comprises an anode plate (110) and a cathode plate (120) spaced apart from each other, and an insulating support member (130) by which the anode plate (110) and the cathode plate (120) are integrally fixed. A vacuum-tight chamber is formed with the anode plate (110), the cathode plate (120) and the insulating support member (130). The anode plate (110) comprises a base (112) formed from transparent ceramic material and an anode conductive layer (114) disposed on one surface of the base (112). The cathode plate (120) comprises a substrate and a cathode conductive layer disposed on a surface of the substrate. The anode conductive layer (114) and the cathode plate (120) are disposed opposite each other. Because transparent ceramic has the advantages of good electrical conductivity, high light transmittance, stable electron-impact resistance performance and uniform luminescence, using transparent ceramic as the base of the anode plate in the field emission light source device can increase electron beam excitation efficiency effectively, increase light extraction efficiency of the field emission light source device, and finally increase its luminous efficiency. A manufacturing method of the field emission light source device is also provided.
