<p>Provided is an image display device, the lifetime of which is extended while the occurrences of luminance unevenness on the screen and crosstalk are suppressed. The image display device comprises an organic EL element (1), a driving transistor (2), a Vth compensation transistor (3A), and a capacitor (4). The organic EL element (1) has a light-emitting luminance that changes depending on the amount of current. The driving transistor (2) adjusts, by the voltage applied to a third electrode, the amount of current flowing between a first electrode electrically connected to the organic EL element (1) and a second electrode, thereby controllingthe amount of current flowing through the organic EL element (1). The Vth compensation transistor (3A) adjusts, by the voltage applied to a sixth electrode, the amount of current flowing between a fourth electrode electrically connected to the first electrode and a fifth electrode electrically connected to the third electrode. The capacitor (4) has a seventh electrode electrically connected to the third electrode and an eighth electrode. The value of the parasitic capacitance (3Ags) between the fifth electrode and the sixth electrode is set to a larger value than the value of the parasitic capacitance (3Agd) between the fourth electrode and the sixth electrode.</p> |
