  • Patent number: 6903504
    Abstract: A covering layer for insulating between column wirings and device electrodes is formed in a region including each cross point of the column wirings and row wirings and under the column wirings. Thus, when an electron source plate in which a large number of electron-emitting devices are wired in passive matrix is formed, a defect resulting from an interaction between the device electrodes and the column wirings at the time of wiring formation is reduced to improve insulation reliability. Therefore, a high quality image is obtained by a large size and higher density pixel arrangement in an image-forming apparatus using the electron source plate.

  • Patent number: 6885141
    Abstract: A cathode ray tube comprises a panel; a funnel engaged to the panel for forming a vacuous space; and a shadow mask supported in the cathode ray tube by being fixed to a mask frame and including an effective surface having a plurality of electron beam passing holes at a center thereof, an ineffective surface formed at a periphery of the effective surface and not having the electron beam passing holes and a skirt portion extended from the ineffective surface towards a vertical direction thereof and welded to the mask frame. In the cathode ray tube, a slot of a predetermined size is formed between welding points by which the skirt portion is welded to the mask frame, and a height of the slot from an end of the skirt portion is higher than a height of the welding points, thereby reducing a doming effect of the shadow mask, reducing a mis-landing which the electron beam does not land to a precise landing point, and thus preventing a color purity of a screen from being deteriorated.
