1. An image display device, comprising:
- a plurality of pixel elements arranged in rows and columns;
a plurality of gate lines, arranged corresponding to the rows of pixel elements and driven to a selected state in a prescribed sequence, each for transmitting, when selected, a select signal for driving pixel elements of a corresponding row to a selected state;
non-select transition detect circuitry arranged for said plurality of gate lines for detecting transition of a gate line in a selected state to a non-selected state; and
internal circuitry for performing an operation related to next image data writing in response to said non-select transition detect circuitry detecting the transition to the non-selected state.

Abstract
Pixels are arranged in rows and columns and gate lines are arranged corresponding to the rows of pixels in a display panel. Deactivation transition detect circuit detects transition of a selected gate line from a selected state to a non-selected state in the gate lines. An operation related to data writing in the next cycle is started in accordance with a deactivation transition detect signal detecting the transition. In an active matrix type display device, a write margin for data writing of the next cycle is increased when a selected gate line transits to a non-selected state.
