1. A display apparatus comprising:
first initialization voltage lines each of which extends in a first direction, wherein the first initialization voltage lines are sequentially arranged in a second direction intersecting the first direction;
second initialization voltage lines extending in the first direction, wherein the second initialization voltage lines are disconnected from the first initialization voltage lines;
a first initialization connection line extending in the second direction, wherein the first initialization connection line electrically connects the first initialization voltage lines to each other;
a second initialization connection line extending in the second direction, wherein the second initialization connection line electrically connects the second initialization voltage lines to each other; and
pixels electrically connected to the first initialization voltage lines and the second initialization voltage lines,
wherein a first initialization voltage transmitted through the first initialization voltage lines and a second initialization voltage transmitted through the second initialization voltage lines are respectively applied to two different transistors of each of the pixels,
wherein a first group of the pixels through which the first initialization connection line passes are electrically connected to a first initialization voltage line by the first initialization connection line, and
wherein the display apparatus further comprises first auxiliary initialization connection lines located in a second group of the pixels through which the first initialization connection line does not pass, wherein the first auxiliary initialization connection lines are electrically connected to the first initialization voltage line.
