PROBLEM TO BE SOLVED: To achieve high luminance light emission by improving used ratio of phosphor light emission based on electron emission from an electron emitter in a light source using the electron emitter. SOLUTION: A light source 10A has a transparent substrate 40, a fixed substrate 82 disposed in facing relation to the transparent substrate 40, a plurality of electron emitters 12 disposed on a main surface side of the fixed substrate 82. An optical reflection film 120 is formed on a part on a main surface of the fixed substrate 82 on which the electron emitters 12 are not formed. Anode electrodes 124 by transparent electrodes 122 are formed over a whole surface of a back surface of the transparent substrate 40. Phosphor 126 is formed in a position facing the electron emitters 12 among the anode electrodes 124. COPYRIGHT: (C)2007,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To provide a method for preventing pixels which are not displayed from appearing in a linear form. SOLUTION: The method for correcting a display substrate of an electric field emission type display device includes an electronic source having a structure laminated with an electrode 11 on a signal line side, an insulation layer (electron acceleration layer) 12, and an electrode 13 of a scanning line side in this order. Relating to the electronic source in which the electrode 13 on the scanning line side and the electrode 11 on the signal line side are shorted by a defect 16 in this case, the conduction of the electrode 13 on the scanning line side and the electrode 11 on the signal line side is cut off. More specifically, the electrode 13 on the scanning line side around (80) the defect portion 16 is excised by a laser beam. The intrinsically normal display element is normally actuated to suppress the occurrence of the linear pixel defect by isolating the display element having the defect. COPYRIGHT: (C)2006,JPO&NCIPI
