1. A liquid crystal display device comprising:

  • a first pixel and a second pixel which is adjacent to the first pixel, each of the first pixel and the second pixel comprising;

    a first wiring;

    a first insulating film over the first wiring;

    a second wiring over the first insulating film, the second wiring being perpendicular to the first wiring;

    a transistor comprising a gate electrode, a gate insulating film, a semiconductor layer, a source electrode, and a drain electrode;

    a second insulating film over the first insulating film and the transistor;

    a third insulating film over the second insulating film; and

    a substrate over the third insulating film,wherein the second wiring in the first pixel is spaced from the second wiring in the second pixel,wherein the second wiring in the first pixel and the second wiring in the second pixel are electrically connected to each other with a connection electrode which is located over the second insulating film,wherein the first insulating film and the gate insulating film exist in the same layer,wherein the third insulating film is located over the connection electrode,wherein the third insulating film is configured to adjust a cell gap of the liquid crystal display device, andwherein the third insulating film is in contact with the connection electrode and the substrate.
