Light emitter substrate with different gaps between metal backs and image displaying apparatus using the same

A light emitter substrate comprising:

• a substrate;
• plural light emitter layers arranged in a first direction and in a second direction perpendicular to the first direction respectively at gaps, on the substrate;
• a rib arranged between the light emitter layers adjacent in the second direction and extending 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 respectively at gaps;
• 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 substrate, 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 volume resistance of the rib, and
• when a gap between the metal backs in the second direction is Gx and a gap between the metal backs in the first direction is Gy, a relation Gx<Gy is satisfied.
