Zusammenfassung:The invention relates to the field of liquid crystal materials and application thereof, in particular to a high-contrast positive liquid crystal composition and application thereof. The liquid crystal composition provided by the invention at least comprises one or more compounds represented by a general formula I, a general formula II and a general formula III, in the general formula I, n is equal to 1-7, and R1 and R2 respectively and independently represent straight-chain alkyl of C1-C12, straight-chain alkoxy or straight-chain alkenyl of C2-C12; in the general formula II, R3 independently represents linear alkyl of C1-C12; l1 independently represents H or methyl; m and n independently represent 0 or 1; a2 and A3 independently represent any one of the following substituents; and in the general formula III, R4 and R5 independently represent a straight chain alkyl group of C1 to C12, a straight chain alkoxy group or a straight chain alkenyl group of C2 to C12, and A4 and A5 independently represent a trans-1,
