摘要： A magnetic material section is provided on a mask substrate so as to be interposed between Y aperture lines of the mask substrate and between X aperture line of the mask substrate. A portion of the magnetic material section which portion is interposed between the X aperture lines has a first thickness and a second thickness which is less than the first thickness, the first thickness being that of each sub-portion thereof which is positioned between mutually adjacent ones of the Y aperture lines, the second thickness being that of each sub-portion thereof which is positioned between apertures which are mutually adjacent in a Y direction.

摘要： Based on the results of detection of characteristics of drive transistors and organic EL elements, a control circuit finds magnitudes of threshold shifts of the drive transistors and the organic EL elements. A power supply voltage control unit sets a value of a low-level power supply voltage to a value lower, by a voltage value corresponding to an average value of the magnitudes of the threshold shifts for all pixels, than a value at an initial point in time. Furthermore, the power supply voltage control unit adjusts a value of a high-level power supply voltage, depending on magnitudes of mobilities obtained by detection of characteristics of the drive transistors.

摘要： The purpose of the present invention is to suppress the fluctuation of a data line voltage that occurs when an analog voltage signal is sampled and held in a data line in a display device provided with a current-driven display element. Transistors (SWr, SWG, SWb) of each demultiplexer (252) are successively switched on, for each predetermined period, in a selection period of a write control line (SW_LR(i)). In a period when the transistor (SWr) is switched on, an analog video signal (Dj) from a data voltage output unit circuit (211d) is applied to a data line (SLrj) and a pixel circuit (50r). When the transistor SWr is then switched off, the voltage held by the data line (SLrj) decreases below the voltage of the analog video signal (Dj) due to a parasitic capacitance (Cssdr). However, the voltage of a voltage fluctuation compensation line (G3_Cnt (i)) changes from a low level to a high level within the selection period. This causes the voltage of the data line (SLrj) to rise via a capacitor (Ccnt), and the decrease in voltage to be compensated for.

摘要： An object of the present invention is to implement a display device capable of compensating for degradation of circuit elements without causing a grayscale failure. Based on the results of detection of characteristics of drive transistors and organic EL elements, a control circuit (20) finds magnitudes of threshold shifts of the drive transistors and the organic EL elements. A power supply voltage control unit (201) sets a value of a low-level power supply voltage (ELVSS) to a value lower, by a voltage value corresponding to an average value of the magnitudes of the threshold shifts for all pixels, than a value at an initial point in time. Furthermore, the power supply voltage control unit (201) adjusts a value of a high-level power supply voltage (ELVDD), depending on magnitudes of mobilities obtained by detection of characteristics of the drive transistors.
