1. A liquid crystal display device, comprising:

  • a display-device substrate including a transparent substrate, a transparent resin layer formed on the transparent substrate, and a transparent electrode formed on the transparent resin layer;

    an array substrate including a source line, a gate line, a pixel electrode positioned in each of pixel openings defined by the source and gate lines, a first insulation layer formed between the source line and the pixel electrode in a cross-sectional view, and a conductive line parallel to the source line and formed on the first insulation layer in a portion where pixel electrodes are divided in a plan view;

    a liquid crystal layer sandwiched between the display-device substrate and the array substrate and including liquid crystal molecules having negative dielectric anisotropy and initially aligned vertically; and

    a controller configured to drive the liquid crystal layer by supplying an image signal to the source line and applying a liquid crystal driving voltage across the transparent electrode and the pixel electrode in synchronization with the image signal,wherein the controller is configured to apply a voltage to the conductive line after the liquid crystal driving voltage is applied to the pixel electrode and while the liquid crystal driving voltage is not applied to the pixel electrode, such that an electric field oriented in a direction traversing the source line in the plan view is generated between conductive lines.
