    • An optical element array includes a first optical element (111) and a second optical element (112) that is further away from a center of an array region than the first optical element (111). Orthogonal projections of the first and second optical elements (111, 112) include first and second ends (201, 202) and third and fourth ends (203, 204), respectively, and vertices thereof are at first and second positions. An interval between the third end (203) and the second position is smaller than that between the first end (201) and the first position and that between the fourth end (204) and that second position. The first and second optical elements (111, 112) respectively include first and second outer edges (241, 242) extending from the vertices thereof to the second and fourth ends (202, 204). A radius of curvature, or a median value of the radius of curvature, of the second outer edge (242) is in the range of 80% to 120% of that of the first outer edge (241).
    • 光学元件阵列包括第一光学元件(111)和比第一光学元件(111)更远离阵列区域的中心的第二光学元件(112)。 第一和第二光学元件(111,112)的正交投影分别包括第一和第二端(201,202)和第三和第四端(203,204),并且其顶点处于第一和第二位置。 第三端(203)与第二位置之间的间隔小于第一端(201)与第一位置之间的间隔以及第四端(204)与第二位置之间的间隔。 第一和第二光学元件(111,112)分别包括从其顶点延伸到第二和第四端(202,204)的第一和第二外边缘(241,242)。 第二外边缘(242)的曲率半径或曲率半径的中值在第一外边缘(241)的曲率半径的80%至120%的范围内。
