Abstract:
In each pixel region, (i) a first pixel electrode (17a) connected to a first transistor (12a), (ii) a second pixel electrode (17b) connected to a second transistor (17b), (iii) a coupling electrode (67y), and (iv) first and second capacitor electrodes (67x and 67z) provided in a layer in which a data signal line (15) is provided, being provided, a capacitor being defined by the coupling electrode (67y) and the second pixel electrode (17b), the coupling electrode (67y) being connected to the first pixel electrode (17a) via a third transistor (112), the first capacitor electrode (67x) and a retention capacitor line (18) overlapping each other via a gate insulating film, the first capacitor electrode (67x) being connected to the first pixel electrode (17a), the second capacitor electrode (67z) and the retention capacitor line (18) overlapping each other via the gate insulating film, the second capacitor electrode (67z) being connected to the second pixel electrode (17b). This allows an increase in pixel aperture ratio of a capacitively coupled active matrix substrate having three transistors.
Abstract(Chinese):
