Field emission type surface light source device and image display apparatus employing the same

An image display apparatus comprising:

• a backlight unit;
• and
• a display panel for forming an image by using light emitted from the backlight unit;
• wherein the backlight unit comprises:
• a first substrate and a second substrate that are disposed to face each other, wherein each of the first substrate and the second substrate comprises:
• a top surface;
• a bottom surface;
• and
• a plurality of lateral sides;
• a sealing member that seals the first substrate and the second substrate;
• first electrodes and second electrodes that are disposed on the first substrate such that the first electrodes and the second electrodes cross each other in an insulated state;
• electron emitters that are electrically connected to one of the first electrodes and the second electrodes;
• a phosphor layer that is disposed on one surface of the second substrate;
• a third electrode that is disposed on one surface of the phosphor layer;
• and
• a first terminal and a second terminal that are electrically connected the first electrodes and the second electrodes, respectively, and are disposed on the top surface and extend to a same lateral side of the plurality of lateral sides of the first substrate outside of a region sealed by the sealing member.
