Display apparatus including dummy pixels and repair lines

摘要

A display apparatus includes: pixels at a display area; dummy pixels at a dummy area; and repair lines coupled to the dummy pixels and connectably arranged to the pixels, each of the dummy pixels including: a driving transistor configured to output a driving current corresponding to a data signal applied to a gate electrode thereof; an emission control transistor between a connection node of a corresponding repair line of the repair lines and the driving transistor, configured to be controlled by an emission control signal; a bypass transistor between the connection node and a first initialization voltage line through which a first initialization voltage is supplied, configured to be controlled by an initialization control signal; and a coupling removal transistor between the connection node and the first initialization voltage line, configured to be controlled by a coupling control signal applied at a different timing from the initialization control signal.
