PROBLEM TO BE SOLVED: To provide a liquid crystal display device with an increased pixel aperture ratio, and a liquid crystal display device that displays an image with high contrast and high luminance.SOLUTION: The liquid crystal display device includes a first pixel electrode, a second pixel electrode, a transistor, a capacitor, a first insulating film, a second insulating film, and a third insulating film. The transistor includes a gate electrode, a gate insulating film, a first oxide semiconductor film, and a source electrode and a drain electrode. One of a pair of electrodes of the capacitor includes a second oxide semiconductor film. The first insulating film is provided over the first oxide semiconductor film. The second insulating film is provided over the second oxide semiconductor film such that the second oxide semiconductor film is sandwiched between the first insulating film and the second insulating film. The third insulating film overlaps an end of the first pixel electrode. The second pixel electrode is provided over the third insulating film.SELECTED DRAWING: Figure 1 |
