1. A liquid crystal display device, comprising:
a first substrate including;
a semiconductor layer,a first insulating film covering the semiconductor layer,a gate line extending in a first direction on the first insulating film,a second insulating film covering the gate line,a source line extending in a second direction orthogonally crossing the first direction on the second insulating film,a contact portion formed on the second insulating film, the contact portion contacting with the semiconductor layer,a third insulating film covering the source line and exposing the contact portion and the second insulating film in a circumference of the contact portion,a sub-common electrode extending in the first direction so as to face the gate line and crossing the source line on the third insulating film,a first main-common electrode connected with the sub-common electrode and extending along the source line in the second direction on the third insulating film,a fourth insulating film covering the sub-common electrode and the first main-common electrode,a second main-common electrode extending in the second direction on the fourth insulating film, the second main-common electrode facing the source line and being set to the same potential as the first main-common electrode,a pixel electrode including a main pixel electrode apart from the second main-common electrode and extending in the second direction on the fourth insulating film, the pixel electrode being electrically connected with the contact portion, anda first alignment film covering the second main-common electrode and the pixel electrode, a second substrate arranged so as to face the first substrate; and a liquid crystal layer held between the first substrate and the second substrate. |
