Patent attributes
A display device comprising a plurality of pixels, each pixel containing a light emitting element and a plurality of substantially rectangular shaped circuit areas, the circuit areas comprising two current mirror circuit areas and two input pair circuit areas; the two current mirror circuit areas abutting each other so as to have a side of their rectangular areas in common, the two input pair circuit areas abutting each other so as to have a side of their rectangular areas in common, with both of the input pair circuit areas abutting a respective one of the current mirror circuit areas so as each to have a side of their rectangular areas in common. This arrangement of circuit areas overcomes the problem of spatial variation of TFT characteristics while avoiding the use of compensating circuits. Additionally, this arrangement of circuit areas can reduce to a minimum the p-type and n-type doping area required within each pixel.
