Abstract

수평 라인 드라이버는 제2 방향으로 표시 패널의 상측에 위치하는 제1 측면 표시 영역에 속하는 제1 내지 제j 스캔 라인들에 스캔 신호를 제공하고, 제1 방향으로 표시 패널의 일측 위치하며, 제1 출력 버퍼를 각각 포함하는 제1 내지 제j 스캔 신호 출력 블록들, 제2 방향으로 곡선 형상의 모서리들을 포함하는 제1 전면 표시 영역에 속하는 제j+1 내지 제k 스캔 라인들에 스캔 신호를 제공하고, 제1 방향으로 표시 패널의 일측에 위치하며, 제2 출력 버퍼를 각각 포함하는 제j+1 내지 제k 스캔 신호 출력 블록들, 및 제2 방향으로 곡선 형상의 모서리들을 포함하지 않는 제2 전면 표시 영역에 속하는 제k+1 내지 제m 스캔 라인들에 스캔 신호를 제공하고, 제1 방향으로 표시 패널의 일측에 위치하며, 제3 출력 버퍼를 각각 포함하는 제k+1 내지 제m 스캔 신호 출력 블록들을 포함한다. 이 때, 제1 측면 표시 영역의 제1 방향으로의 너비는 제1 전면 표시 영역의 제1 방향으로의 너비보다 작고, 제1 전면 표시 영역의 제1 방향으로의 너비는 제2 전면 표시 영역의 제1 방향으로의 너비보다 작으며, 제1 전면 표시 영역의 제1 방향으로의 너비는 제2 전면 표시 영역에 가까워질수록 커진다.
