Abstract: The present application discloses an active matrix type display device that is capable of successfully displaying an image by an intra-screen division drive while suppressing the complication of a circuit configuration. In a liquid crystal panel that includes an A area and a B area, an A area scanning signal line and a B area scanning signal line are scanned in the same direction, and the A area data signal line and the B area data signal line are driven based on an A area image signal DaA and a B area image signal DaB, respectively, that are obtained from an image signal DA from the outside. Furthermore, when a scanning signal line that is to be selected latest in the A area is selected, a voltage that is the same as a data signal voltage which is applied to the A area data signal line that intersects the scanning signal line is applied to the B area data signal line that is paired with the A area data signal line.

Abstract: Modified PTFE is produced by exposing a starting PTFE to an ionizing radiation for a total dose of at least 100 kGy in the absence of oxygen at a temperature not lower than the crystal melting point of the starting PTFE. The thus modified PTFE is improved in radiation resistance and has rubber characteristics.
