Abstract:
A grating and a display device. The grating (200) comprises periodical cycle arrangements. The first period of the grating is taken as the minimum cycle period and includes two rows of grating structures having same grating pitch and same grating slit width. In the first period, the second row of grating structures are shift to the right or left the distance “c” compared with the first row of grating structures, and the calculation method of “c” is: c=b, in which “b” refers to the width of a sub-pixel in a display panel. The first row of grating structures of the ith period are shift to the right or left the distance “d” compared with the first row of grating structures of the first period, and the calculation method of “d” is: d=2(i−1)b, in which i is an integer and i≧2. The grating and the display device can effectively reduce the Moire phenomenon.
