Matrix type display apparatus

A matrix type luminescent material display apparatus comprising:

• a first substrate having a first main surface and a second main surface substantially parallel to the first main surface;
• and
• a second substrate arranged to be opposed to the first main surface of the first substrate while maintaining a predetermined gap therebetween in vacuum, having a third main surface opposed to the first main surface and a fourth main surface substantially parallel to the third main surface and made of a transparent material,
• the first substrate comprising:
• a plurality of scanning line wirings provided on the first main surface and parallel to each other;
• a plurality of signal line wirings provided on the first main surface in a direction crossing the plurality of scanning line wirings, and parallel to each other;
• a plurality of display pixels defined at respective intersections of the plurality of scanning line wirings and the plurality of signal line wirings, formed of field emission type electron sources, and independent of each other;
• and
• a plurality of back side wirings provided on the second main surface and connected with at least one of the plurality of scanning line wirings and the plurality of signal line wirings at opposed end portions of the first substrate,
• the second substrate comprising:
• an anode electrode formed on the third main surface to apply a voltage;
• and
• an electron beam excited type luminescent material layer formed on the third main surface.
