ELECTRO-OPTICAL DEVICE, SHIFT REGISTER CIRCUIT, AND SEMICONDUCTOR DEVICE

摘要

An electro-optical device is configured to be capable of using a region of a gate line drive circuit efficiently and preventing rising speed of a gate line selection signal from decreasing (rising delay), and a shift register circuit is composed of a single conductivity type transistor which is suitable for the device. The gate line drive circuit including an odd driver to drive odd rows of a plurality of gate lines, and an even driver to drive even rows thereof. Each unit shift register in the odd and even drivers receives a selection signal in the second previous row and activates its own selection signal two horizontal periods later. A start pulse of the even driver is delayed in phase by one horizontal period with respect to a start pulse of the odd driver.
