A porous polyester film having an apparent specific gravity of not more than 1.3, which comprises a polyester film having many voids (layer (A)) comprising a polyester and a thermoplastic resin incompatible with said polyester, and a polyester film having many fine voids (layer (B)) comprising a polyester and inorganic fine particles having an average particle size of not more than 1 &mgr;m, the two layers being bonded to each other, wherein the layer (B) has a porosity of not less than 20% by volume, and a thickness of 1-20 &mgr;m that is not more than 30% of the thickness of the porous film. Due to the present invention, a porous polyester film capable of providing an image-receiving sheet superior in surface smoothness, image density, and resistance to wrinkles can be provided.

A porous polyester film containing a polyester resin as a main starting material is provided. By optimizing the melt viscosity of a void-forming agent to be added, the ratio of the number of voids to film thickness can be set to 0.20 void/μm or above. As a result a lightweight polyester film can be provided, which has a high strength, superior processability and high reflectivity to visible light. This film is suitable as a material for various reflectors.

A recording material comprising a substrate and an ink receiving layer formed thereon, wherein said substrate has a thickness of 38-200 &mgr;m, said ink receiving layer is a porous layer comprising particles and a resin and has a thickness of not less than 40 &mgr;m and not more than 105 &mgr;m, and wherein the recording material has a curl value of not more than +10 mm, and a recording material comprising a substrate and an ink absorption layer formed thereon, wherein the ink absorption layer has a surface strength of not less than 80 g weight/cm. The recording material thus obtained affords sharp recording of images having extremely high water resistance and free of bleeding by the ink jet recording method particularly using oily ink. The material hardly curls even under severe environment associated with radically changing humidity, temperature and the like, thereby ensuring stable transportability of the recording material without trouble caused by being in contact with a priting head. When used as an illumination signboard, moreover, the recording material affords superior images that are maintained when the illumination signboard is on or off.

A stage of the shift register has (i) a set-reset type flip-flop which receives an initialization signal and (ii) a signal generating circuit which receives a simultaneous selection signal and which generates an output signal by use of an output of the flip-flop. In at least one example embodiment, the output of the flip-flop becomes inactive regardless of whether a setting signal and a resetting signal are active or inactive, as long as the initialization signal is active. The initialization signal becomes active before the end of the simultaneous selection, and then becomes inactive after the end of the simultaneous selection. This makes it possible to stabilize operation of the shift register after the end of simultaneous selection of a plurality of signal lines carried out by the display driving circuit at a predetermined timing.

In one embodiment of the present invention, on each source bus line, an electric charge escaping transistor is provided having the same polarity as a pixel transistor and having a gate to which a turn-off voltage signal of the pixel transistor is supplied. When an active matrix liquid crystal display device is powered off, the turn-off voltage signal is made to reach the GND level before a turn-on voltage signal of the pixel transistor reaches the GND level, so that the pixel transistor and the electric charge escaping transistor are made half-open. This lets electric charges accumulated in the pixel escape to a common electrode TCOM.

A display driving circuit of the present invention includes: a source driver (20) which outputs a source signal; a gate driver (30) which outputs a gate signal for turning on a switching element on a row; and a CS driver (40) which outputs a CS signal (CSOUT) whose electric potential is switched in a predetermined direction (low to high or high to low) in accordance with a polarity of the source signal. A CS driver (CSn) on an n-th row outputs a CS signal (CSOUT) to the n-th row in accordance with a gate signal (GLn) for the n-th row outputted from a gate driver (Gn) provided on the n-th row. This makes it possible to provide a display driving circuit which enables CC driving with a simple configuration.
