  • Patent number: 5502583
    Abstract: In an active matrix liquid crystal display device incorporates a plurality of thin-film transistors, drain lines, and display electrodes of a conductive material. Compensating lines of the conductive material are wider than the drain lines and are formed on the drain lines simultaneously with the display electrodes. A predetermined distance is defined between the display electrode and the compensating line for each of the thin-film transistors. The predetermined distance is further defined between the display electrode for one of the thin-film transistors and the compensating line for an adjacent one of the thin-film transistors. The adjacent one of the thin-film transistors is nearer to the display electrode for the thin-film transistor in question rather than the drain line for the thin-film transistor in question.
