1. A liquid crystal display device, comprising:

  • a first substrate unit;

    a second substrate unit provided to oppose the first substrate unit; and

    a liquid crystal layer provided between the pair of substrate units,the first substrate unit including;

    a first major surface;

    a plurality of pixel electrodes arranged in a matrix configuration in the first major surface, a row direction of the matrix being an X-axis direction, a column direction of the matrix being a Y-axis direction intersecting the X-axis direction; and

    an alignment film covering the pixel electrodes and opposing the liquid crystal layer,the pixel electrodes including a first pixel electrode and a second pixel electrode arranged to be adjacent along one of the row direction or the column direction, the first pixel electrode and the second pixel electrode being driven by mutually-different polarities, an inter-pixel region being provided to extend in the column direction between the first pixel electrode and the second pixel electrode,the second substrate unit including;

    a second major surface opposing the first major surface of the first substrate unit;

    a plurality of counter electrodes disposed in the second major surface, the counter electrodes being light-transmissive; and

    an alignment film covering the counter electrodes and opposing the liquid crystal layer,the counter electrodes including a first opposing portion and a second opposing portion, the first opposing portion and the second opposing portion opposing the pixel electrodes of the first substrate unit, being provided to extend in one of the row direction or the column direction, and being arranged to be adjacent to each other along the other of the row direction or the column direction,an inter-counter electrode region being provided between the first opposing portion and the second opposing portion, the inter-counter electrode region and the inter-pixel region of the first substrate unit overlapping when projected onto the first major surface,a light-shielding layer being provided along the other of the row direction or the column direction in the second substrate unit, the light-shielding layer extending in the column direction and covering the inter-counter electrode region and the inter-pixel region.
