摘要

A display includes: a light-emitting element; a first data signal line to which a signal corresponding to video data is supplied in a vertical scanning period and a signal not corresponding to video data is supplied in an update pause period; a drive transistor configured to control a current value of the light-emitting element; and a conductor electrically connected to a gate electrode of the drive transistor; a shield electrode located between the first data signal line and the conductor and adjacent to each of the first data signal line and the conductor in a plan view.

FIG. 9 is a plan view illustrating a configuration of a TFT layer according to a third embodiment. FIG. 10 is a cross-sectional view taken along an arrow in FIG. 9. Although the shield electrode A1 is extended from the scanning signal line GXn in the first and second embodiments, this is not a limitation. As in the third embodiment, a shield electrode A3 may be provided to extend from the scanning signal line GYn-2 (scanning signal line for controlling the transistor T1 in the current stage and the transistor T2 in the second preceding stage, see FIG. 2) included in the third metal layer K3 to between the data signal line DLi and the conductor LE in a plan view.

In the third embodiment, the shield electrode A3 is included in the third metal layer K3, so that it is less likely to be short-circuited with the data signal line DLi included in the fourth metal layer K4 and the conductor LE included in the second metal layer K2.

The embodiments described above are for the purpose of illustration and description and are not intended to be limiting. It will be apparent to those skilled in the art that many variations will be possible in accordance with these examples and descriptions.
