1. active matrix type display is characterized in that having:

  • Matrix type ground is provided with the pixel portions of a plurality of pixels have light-emitting component and to drive the 1st thin-film transistor of this light-emitting component,Have electroluminescence layer on the 1st electrode, described the 1st electrode, and described electroluminescence layer on the monitor element of the 2nd electrode,Drive the 2nd thin-film transistor of described monitor element,Described monitor element is flow through the constant-current supply of certain electric current, andAmplifier,Described constant-current supply is electrically connected to the source electrode of described the 2nd thin-film transistor and a side of drain electrode, and the input of described amplifier,The source electrode of described the 2nd thin-film transistor and the opposing party of drain electrode are electrically connected to a side'"'"'s of described monitor element electrode,One side'"'"'s of described light-emitting component electrode is electrically connected to the output of described amplifier through described the 1st thin-film transistor,Described monitor element and described the 2nd thin-film transistor are not set mutually overlappingly,The 1st photomask is set, makes the 1st electrode of itself and described monitor element overlapping,The 2nd photomask is set, makes it overlap the end of described the 1st electrode of described monitor element.
