Abstract
Official abstract text for this publication.
A display device includes a light-emitting element, a data line, a wiring line, a first constant potential line to which a first constant potential is supplied, a first transistor configured to supply a drive current corresponding to a video signal supplied via the wiring line and the data line to the light-emitting element, a second transistor configured to electrically couple the data line to the first constant potential line, and a switching element configured to electrically couple the data line to the wiring line.
First claim
Opening claim text (preview).
What is claimed is: 1. A display device, comprising: a light-emitting element; a data line; a wiring line; a first constant potential line to which a first constant potential is supplied; a first transistor configured to supply a drive current to the light-emitting element, the drive current corresponding to a video signal supplied via the wiring line and the data line; a second transistor configured to electrically couple the data line to the first constant potential line; a third transistor configured to control supply of the video signal to the wiring line and the data line; a capacitance element including a first electrode electrically coupled to the wiring line, and a second electrode disposed to face the first electrode, and electrically coupled to the third transistor; and a switching element configured to electrically couple the data line to the wiring line, the switching element being electrically coupled between the second transistor and the first electrode of the capacitance element. 2. The display device according to claim 1 , further comprising: a second constant potential line to which a second constant potential is supplied; and a fourth transistor configured to electrically couple the first electrode to the second constant potential line. 3. The display device according to claim 1 , further comprising: a third constant potential line to which a third constant potential is supplied; and a fifth transistor configured to electrically couple the second electrode to the third constant potential line. 4. The display device according to claim 1 , further comprising a second switching element, wherein the data line is divided into a plurality of data lines, and each of the plurality of data lines is coupled to another data line via the second switching element. 5. The display device according to claim 1 , wherein the data line is divided into a first data line and a second data line, and the display device further includes a third switching element that electrically couples the first data line to the second data line. 6. An electronic apparatus comprising: the display device according to claim 1 ; and a control unit configured to control operation of the display device.
