Abstract: The photolithography processes for connecting the first conductive film pattern, which is a lower layer such as a gate electrode of a TFT, to a second conductive film pattern, which is an upper layer such as a source/drain electrode of a TFT are reduced by utilizing laminated films and a resist pattern formed thereon having different film thicknesses. Laminated films constituting the source/drain electrode are formed by depositing films on an insulating substrate on which the first conductive film pattern is formed, and the resist pattern is formed on the top layer of the laminated films, and then utilizing the film thickness difference of the resist pattern and the film composition of the laminated films, the short circuited wiring between the gate electrode and the source/drain electrode for an Electro-Static-Discharge protection circuit of the active matrix substrate can be formed by less photolithography processes than that in the manufacturing of the conventional active matrix substrate.

Abstract: A liquid crystal display is provided which has low power consumption, and which prevents horizontal stripes from occurring without the circuitry becoming more complex. When the write voltage polarity is inverted every plurality of lines, in the n line where the polarity is inverted, the rise in the drain line waveform dulls due to the charging of the drain line. In the n+1 line, because the drain line has been charged by the writing of the n line, waveform dullness does not occur. A difference between the write states in the two lines causes horizontal stripes. Consequently, the output enable signal is activated at the rise of the clock signal, and the gate line is activated after a predetermined time to start the writing. Therefore, writing is not performed during the period of waveform dullness, and the write state is the same across all scan lines.
