摘要： A pixel includes a light emitting element and a driving element connected to the light emitting element. After an initial voltage is applied to one end of a current path of the driving element via the signal line, the pixel driving device acquires the threshold voltage of the driving element based on a voltage value at a terminal of the signal line when the initial voltage is cut off and the relaxation time is elapsed. The voltage-current characteristics of the driving element is acquired based on the voltage value at the terminal of the signal line when the current flows into the current path of the driving element via the signal line. The current gain value of the driving element is acquired based on the threshold voltage of the driving element. The image data is corrected based on the acquired threshold voltage.

摘要： A light-emitting element capable of emitting light having a preferred gradation level depending on display data. During a precharge period, a data driver applies a precharge voltage to a capacitor via a data line. After the application of the precharge voltage, a voltage converter reads a first reference voltage Vref(t1) and a second reference voltage Vref(t2) to generate a compensation voltage based on a difference between the respective reference voltages. Based on the compensation voltage, a voltage calculator compensates an original gradation level voltage Vorg having a value in accordance with display data generated by a gradation level voltage generator. The voltage calculator generates a compensated gradation level voltage Vpix corresponding to a variation amount of an element characteristic for a transistor Tr13 for driving light emission to apply the compensated gradation level voltage Vpix to a data line Ld.

摘要： A liquid crystal cell is formed by bonding a first substrate on which a first electrode and a first aligning film are formed, and a second substrate on which a second electrode and a second aligning film are formed by a seal member. A liquid crystal is filled in the liquid crystal cell. The thicknesses of the aligning films are set to 10 nm to 35 nm. An aligning treatment is performed twice on each of the aligning films in the opposite directions. The first aligning treatment is performed to give a pretilt angle of 5 degrees to the liquid crystal, and the second aligning treatment is performed to give a pretilt angle of 6 degrees to the liquid crystal, with the result that a pretilt angle of 1 degree is actually given to the liquid crystal. The glass-transition temperatures of the aligning films are selected to be about 250.degree. C., so that the aligning films are not transformed at the time of baking the seal member.
