Active matrix-type display panel

Claim 1

An active matrix-type display panel, comprising: a liquid crystal panel comprising: a first base plate having thereon: a plurality of thin film transistors arranged in the form of a matrix comprising rows and columns; a plurality of horizontal lines each commonly connected to the gates of thin film transistors in a row; a plurality of vertical lines each commonly connected to the sources of the thin film transistors in a column; and a plurality of pixel electrodes each connected to the drain of a thin film transistor; a second base plate having thereon a counter electrode; and a liquid crystal disposed between the first and second base plates; a scanning-side driving circuit provided with a first shift register; an information-side driving circuit provided with a second shift register; a plurality of capacitive elements respectively connected to the vertical lines for sampling-and-holding information signals, each capacitive element being formed between one of the vertical lines and the counter electrode with the liquid crystal disposed therebetween and having a capacitance at least thirty times the capacitance formed between one pixel electrode and the counter electrode with the liquid crystal disposed therebetween; a plurality of analog switching transistors disposed between said second shift register and said capacitive elements for holding the information signals at said respective capacitive elements for one scanning period for scanning a row of the transistors; and said plurality of analog switching transistors being divided into a plurality of blocks each comprises a plurality of analog switching transistors ]the gates of which are commonly connected to a switching line, and the sources of which are connected to data lines leading to the second shift register in such a manner that the sources of the analog switching transistors in each block are respectively connected to one of the data lines, and wherein a group of the sources of the analog switching transistors each belonging to a different block are commonly connected to one of the data lines.
