Title (EN) DISPLAY DEVICE COVER SUBSTRATE
(FR) SUBSTRAT DE COUVERTURE DE DISPOSITIF D'AFFICHAGE
(KO) 디스플레이 장치용 커버기판
Abstract: front page image
(EN)The present invention relates to a display device cover substrate and, more specifically, to a display device cover substrate capable of increasing surface hardness by alleviating an internal stress occurring in a reinforcing layer formed on a base of a glass material so as to reinforce the base, thereby preventing the formation of defects and scratches, which cause the formation of cracks. To this end, the present invention provides a display device cover substrate comprising: a base; a reinforcing layer formed on the base and including a tensile stress layer and a compressive stress layer which are alternately stacked; and a buffer layer formed between the base and the reinforcing layer.
(FR)La présente invention concerne un substrat de couverture de dispositif d'affichage et, plus précisément, un substrat de couverture de dispositif d'affichage capable d'accroître la dureté de surface en atténuant une contrainte interne survenant dans une couche de renfort formée sur une base d'un matériau en verre de façon à renforcer la base, empêchant ainsi la formation de défauts et de rayures, qui provoquent la formation de fissures. À cette fin, la présente invention concerne un substrat de couverture de dispositif d'affichage comportant: une base; une couche de renfort formée sur la base et comprenant une couche de contrainte de traction et une couche de contrainte de compression qui sont superposées en alternance; et une couche tampon formée entre la base et la couche de renfort.
(KO)본 발명은 디스플레이 장치용 커버기판에 관한 것으로서 더욱 상세하게는 유리 재질의 기재를 강화시키기 위해, 기재 상에 형성되는 강화층에 발생되는 내부 응력을 완화시킴으로써, 표면 경도를 증가시킬 수 있고, 이를 통해, 크랙 발생의 원인이 되는 결함 및 스크래치 발생을 방지할 수 있는 디스플레이 장치용 커버기판에 관한 것이다. 이를 위해, 본 발명은, 기재; 상기 기재 상에 형성되고, 인장응력층과 압축응력층의 교대 적층으로 이루어진 강화층; 및 상기 기재와 상기 강화층 사이에 형성되는 버퍼층을 포함하는 것을 특징으로 하는 디스플레이 장치용 커버기판을 제공한다.
