PROBLEM TO BE SOLVED: To provide an electro-optic display, and to provide a method for driving the display.SOLUTION: An electro-optic display includes an electro-optic medium, a pixel electrode for applying electric field to the electro-optic medium, and a column electrode associated with the pixel electrode. In order to reduce power consumption, when it is necessary to change voltage on the column electrode from a first value to a second value so as to change an optical state of the electro-optic medium, voltage of the column electrode is first changed to a third value, which is between the first and second values, to permit charge to flow to or from the column electrode, and thereafter the voltage of the column electrode is changed from the third voltage to the second voltage. 【課題】電気光学ディスプレイおよびこのようなディスプレイをドライブする方法を提供すること。【解決手段】電気光学ディスプレイは電気光学媒体、電気光学媒体に電界を印加するためのピクセル電極およびピクセル電極と関連する列電極を含む。電力消費を削減するために、電気光学媒体の光学的状態を変化させるために列電極上の電圧を第１の値から第２の値に変更することが必要なときに、列電極の電圧は最初に第１および第２の値の間の第３の値に変更され、列電極へまたはそこからチャージが流れることを許容し、その後、列電極の電圧は第３の電圧から第２の電圧に変更される。【選択図】図３Ｂ
