Abstract:
A method of manufacturing an electrooptic device comprising a first substrate comprising a display region in which pixel electrodes are arranged, and a peripheral driving circuit region arranged in the periphery of the display region, a second substrate, and an optical material interposed between a first substrate and a second substrate, the method comprising the steps of:forming step portions in one side of the first substrate; depositing a single crystal semiconductor layer on the first substrate including the step portions by graphoepitaxial growth by a catalytic CVD or high-density plasma CVD method using the step portions as seeds; forming channel, source and drain regions in the single crystal semiconductor layer after growth of the single crystal semiconductor layer; and forming gate portions of the channel regions to form top gate type first thin film transistors which constitute at least a portion of the peripheral driving circuit region, wherein the first thin film transistors are respectively provided in the step portions of the first substrate.
