An MVA type liquid crystal display panel of the present invention comprises a first substrate where a light transmission section consisting of a pixel electrode 15a, whose corner portions are chamfered, is formed at each position partitioned by scanning lines 13 and signal lines 14 that are arranged in a matrix state, in which a protruding electrode 40 extending from the pixel electrode 15a is formed between the chamfered position of the corner portion and the scanning line 13 to prevent the inclination of liquid crystal molecules due to the effect of the potential difference occurring between the scanning line and a common electrode. According to the present invention, it is possible to provide an MVA type of liquid crystal display panel having high contrast, where contrast reduction caused by the inclination of liquid crystal molecules due to the effect of the potential difference occurring between the scanning line and a common electrode is controlled, even where the liquid crystal display panel employs pixel electrodes with chamfered corner portions.

A display device includes a plurality of light emitting elements arranged in a matrix. A scan signal is made to flow into a gate signal line and a data signal is made to flow into a source signal line so that the data signal is applied to a source electrode and the scan signal is supplied to a gate electrode of a control TFT arranged at a portion where the both signal lines intersect when viewed from above. Thus, when the control TFT is turned ON, a drive TFT having a gate electrode connected to the drain electrode is turned ON, so that current is supplied from a power supply line via the source electrode and the drain electrode of the drive TFT to an organic EL element and the organic EL element emits light. A holding capacity is present between the control TFT and the drive TFT. Even when the scan signal becomes LOW level and the control TFT turns OFF, the gate potential of the drive TFT is held for a predetermined period of time by the holding capacity and the organic EL element continues to emit light.

More specifically, it is preferable that the spacer member 40 consist of a soda glass substrate and that the liquid crystal display panel 36 for display be formed of non-alkali glass. With this constitution, it is possible to provide a stereoscopic image display device, which can be used as a large-sized stereoscopic image display device by means of the liquid crystal parallax barrier method, with good display quality and where due consideration has been given to the thermal expansion of the substrate caused by heat generated by the backlight, and the manufacturing method therefor.

An idling speed control device of an internal combustion engine comprising a bypass passage which interconnects the intake passage located upstream of the throttle valve to the intake passage located downstream of the throttle valve. A flow control valve is arranged in the bypass passage and actuated by a step motor for controlling the amount of air flowing within the bypass passage to maintain the idling speed of an engine at a predetermined speed. The step motor comprises a screw threaded valve shaft and a rotor rotatably mounted on the valve shaft and having a screw threaded center hole which is in engagement with the screw threads of the valve shaft. A pair of stop pins, each being engageable with the corresponding end face of the rotor, is fixed onto the valve shaft.
