Abstract

To provide a liquid crystal display device capable of generating the transition of a liquid crystal layer from a splay alignment state to a bend alignment state quickly and stably without applying a high driving voltage. The liquid crystal display device is provided with a liquid crystal panel (2) having: a pair of substrates (3, 4), which are arranged oppositely to each other and in which electrodes (19, 25) and alignment layers (21, 26) are formed on respective counter surfaces thereof; an OCB mode liquid crystal layer in which a nematic liquid crystal sealed in between the pair of substrates is splay aligned with the alignment layers and the splay aligned nematic liquid crystal is subjected to the transition to the bend aligned state with the driving voltage applied between the electrodes; and spacers 6 arranged inside the liquid crystal layer and retaining a gap between the pair of mutually opposing substrates uniform. The spacers are subjected to a surface treatment for accelerating the transition of the liquid crystal layer from the splay aligned state to the bend aligned state.
