Abstract
To provide a light emitter substrate which is characterized in that discharge current reduction performance is excellent, plural phosphors are arranged in an X direction and a Y direction on a substrate, metal backs are arranged on the phosphors, ribs extending in the Y direction are arranged between the phosphors adjacent in the X direction, first resistors to electrically connect the metal backs adjacent in the Y direction are formed on the ribs respectively, and second resistors to electrically connect the metal backs adjacent in the X direction are formed under the ribs respectively.
Claims4
A light emitter substrate comprising:
- a substrate;
- a black matrix is formed on the substrate with a plurality of aperture portions;
- plural light emitter layers arranged in a first direction and in a second direction perpendicular to the first direction on the respective aperture portions;
- a rib arranged between the light emitter layers adjacent in the second direction and extending in the first direction;
- plural metal backs each covering at least one of the light emitter layers and arranged in the first direction and in the second direction;
- a first resistor, extending in the first direction, positioned on the rib, adapted to electrically connect the metal backs adjacent in the first direction;
- and
- a second resistor, extending in the second direction, positioned between the ribs and the black matrix, adapted to electrically connect the metal backs adjacent in the second direction,
- wherein volume resistance of the first resistor and volume resistance of the second resistor are lower than a volume resistance of the rib.
