Claim Text:
1. A liquid crystal display device, comprising: a color filter substrate, an array substrate, an upper polarizing sheet arranged at a side of the color filter substrate and a lower polarizing sheet arranged at a side of the array substrate; wherein: the color filter substrate comprises a first graduated scale and a second graduated scale, the array substrate comprises a third graduated scale and a fourth graduated scale, and the first graduated scale, the second graduated scale, the third graduated scale and the fourth graduated scale are arranged within a non-display region; the first graduated scale is configured to measure a distance of at least one first edge of a plurality of first edges, which are parallel with each other, of the upper polarizing sheet to an edge of the color filter substrate closer to the at least one first edge; and the second graduated scale is configured to measure a distance of at least one second edge of a plurality of second edges, which are parallel with each other, of the upper polarizing sheet to an edge of the color filter substrate closer to the at least one second edge; and the third graduated scale is configured to measure a distance of at least one third edge of a plurality of third edges, which are parallel with each other, of the lower polarizing sheet to an edge of the array substrate closer to the at least one third edge; and, the fourth graduated scale is configured to measure a distance of at least one fourth edge of a plurality of fourth edges, which are parallel with each other, of the lower polarizing sheet to an edge of the array substrate closer to the at least one fourth edge.
