Abstract:
An electro-optical element driving circuit which drives a plurality of electro-optical elements arranged in matrix, comprising:a plurality of digital processing means that correspond to respective bits in a digital driving signal for driving each of the electro-optical elements, and which generate a processing digital driving signal by performing predetermined digital processing digital driving signal, a plurality of digital/analog converting means that generate an analog driving signal corresponding to a digital value included in the digital driving signal by digital/analog converting the digital driving signal, and respectively drive the electro-optical elements by respectively applying the analog driving signal to the electro-optical elements; wherein, on the substrate, a plurality of elements which respectively form each digital processing means, each analog switch and each capacitance circuit are arrayed and disposed for each bit in a direction in which signal lines are disposed, and wires among a plurality of wires respectively connected between the elements that are parallel to the direction in which the signal lines are disposed are mutually separated on the substrate, as seen from a plan view.
