본 발명의 디스플레이 장치용 윈도우 커버의 제조 방법은 사출 압축 성형에 의해 제조되며, 상부 금형 및 하부 금형의 온도 차, 형체력, 유지 압력 출력을 조절함으로써 윈도우 커버의 평탄도를 향상시킬 수 있다. 본 발명은 윈도우 커버의 복굴절 성능을 유지하면서도 윈도우 커버의 평탄도를 향상시킬 수 있다.

    A manufacturing method of a window cover for a display device of the present invention is to manufacture a window cover by injection compression molding, and can improve the flatness of the window cover by adjusting temperature difference, clamping force, and holding pressure output between an upper mold and a lower mold. The present invention can improve the flatness of the window cover while maintaining birefringence performance of the window cover.
