Zusammenfassung:The present invention provides a display device. The display device of the present invention is a display device comprising: a light source; a compensating diffractive optical element which reflects light incident from the light source; and an off-axis reflection diffractive optical element which reflects light, reflected by the compensating diffractive optical element, to the outside, wherein the compensating diffractive optical element reflects light, incident from the light source, to the off-axis reflection diffractive optical element while adjusting the angle of reflection of the incident light, so as to compensate for distortion in the angle of reflection of light reflected by the off-axis reflection diffractive optical element. La présente invention concerne un dispositif d'affichage. Le dispositif d'affichage de la présente invention est un dispositif d'affichage comprenant : une source de lumière ; un élément optique diffractif de compensation qui réfléchit la lumière incidente à partir de la source de lumière ; et un élément optique diffractif de réflexion hors axe qui réfléchit la lumière, réfléchie par l'élément optique diffractif de compensation, vers l'extérieur, l'élément optique diffractif de compensation réfléchissant la lumière, incidente provenant de la source de lumière, à l'élément optique diffractif de réflexion hors axe tout en ajustant l'angle de réflexion de la lumière incidente, de façon à compenser la distorsion dans l'angle de réflexion de la lumière réfléchie par l'élément optique diffractif de réflexion hors axe. 본 발명은 디스플레이 장치를 제공한다. 본 발명의 디스플레이 장치는 광원; 상기 광원으로부터 입사되는 광을 반사하는 보상 회절광학소자; 및 상기 보상 회절광학소자에서 반사된 광을 외부로 반사하는 비축 반사 회절광학소자를 포함하고, 상기 보상 회절광학소자는, 상기 비축 반사 회절광학소자에서 반사되는 광의 반사 각도 왜곡이 보상되도록, 상기 광원으로부터 입사되는 광의 반사 각도를 조절하여 상기 비축 반사 회절광학소자로 반사하는 것을 특징으로 하는 디스플레이 장치이다.
