Mounting substrate and electronic apparatus

An electronic apparatus provided with one or a plurality of mounting substrates and a control circuit that controls the one or plurality of mounting substrates, each of the mounting substrates comprising:

• a wiring substrate;
• a plurality of light-emitting elements arranged in a matrix on the wiring substrate;
• and
• a plurality of drive ICs that are arranged in a matrix on the wiring substrate, and control light emission of the light-emitting elements, wherein
• the light-emitting elements and the drive ICs are mounted on a same surface,
• the wiring substrate includes a plurality of first wiring lines on the surface where the light-emitting elements and the drive ICs are mounted, the first wiring lines electrically coupling the light-emitting elements to the drive ICs,
• the wiring substrate includes a plurality of second wiring lines,
• each of the drive ICs controls light emission luminance of at least one of the light-emitting elements, and
• each of the drive ICs controls starting light emission and ending light emission of the at least one of the light-emitting elements, based on a signal inputted via the second wiring lines.
