摘要

A display apparatus includes first to third pixels sequentially arranged in a first direction, a first voltage line which transfers a first initialization voltage, a second voltage line which transfers a second initialization voltage, a first contact plug connecting the first pixel and the second pixel to the first voltage line, and a second contact plug connecting the second pixel and the third pixel to the second voltage line.

說明書

In FIG. 3, the compensation transistor T3 includes two transistors which are connected in series with each other, but the compensation transistor T3 may include one transistor. In another embodiment, the compensation transistor T3 may include three or more transistors that are connected in series with each other.

The gate initialization transistor T4 applies the first initialization voltage VINT1 to the gate of the driving transistor T1 in response to the second scan signal GI_i. The gate initialization transistor T4 may include a gate connected to the second scan line GIL_i, a source S connected to the gate of the driving transistor T1, and a drain D connected to the first voltage line VL1.

The first pixel PXi(j?1) and the second pixel PXij may share the first contact plug CP1 connected to the first voltage line VL1. When the gate initialization transistors T4 of the first pixel PXi(j?1) and the second pixel PXij are turned on in response to the second scan signal GI_i, the first initialization voltage VINT1 received via the first contact plug CP1 may be applied to the gates of the driving transistors T1 of the first pixel PXi(j?1) and the second pixel PXij.
