ABSTRACT:
A tricyclic cyclohexenyl cyclohexane derivative is disclosed. This compound is capable of lowering the .DELTA.n value of mixed liquid crystals, which have been obtained by adding said compound to nematic liquid crystals widely used as matrix liquid crystals, and elevating the N-I point thereof. Thus it is highly useful in the production of liquid crystal display cells.
