Abstract:
The present invention provides a liquid crystal display device that can suppress a display defect due to collapse of liquid crystal alignment. The present invention provides a liquid crystal display device comprising a liquid crystal display element including a pair of substrates and a liquid crystal layer hermetically interposed between the pair of substrates, wherein the liquid crystal layer includes a p-type liquid crystal material that is homeotropically aligned with respect to surfaces of the pair of substrates when no voltage is applied; one of the pair of substrates comprises a comb-shaped electrode and a first alignment layer configured to control alignment of the p-type liquid crystal material; the other of the pair of substrates comprises a second alignment layer configured to control alignment of the p-type liquid crystal material; and the first alignment layer has an anchoring energy of not greater than 1.5×10−4 J/m2.
