First Claim
1. A liquid crystal display device comprising:
- a first substrate;
a second substrate; and
a liquid crystal held between the first substrate and the second substrate, wherein the first substrate hasa transparent pixel electrode formed in each pixel;
a second insulating film covering the transparent pixel electrode;
a common metal wiring line formed on an upper side of the second insulating film; and
a transparent counter electrode opposite to the transparent pixel electrode across the second insulating film, the transparent counter electrode being formed on the second insulating film and the common metal wiring line to electrically connect with the common metal wiring line, whereinthe transparent pixel electrode is connected with a thin film transistor formed in each pixel through a contact hole on a layer lower than the transparent pixel electrode,the transparent counter electrode has multiple slits formed therein and includes a portion located in the contact hole, andat least one of the multiple slits is formed in the portion of the transparent counter electrode.

Abstract
To form a sufficiently large storage capacitor, a liquid crystal display device includes a liquid crystal display panel having a first substrate, a second substrate, and a liquid crystal held between the first substrate and the second substrate, the liquid crystal display panel having multiple pixels arranged in matrix. The first substrate has, in a transmissive display area provided in each of the pixels, a laminated structure containing a first transparent electrode, a first insulating film, a second transparent electrode, a second insulating film, and a third transparent electrode which are laminated in this order. The first transparent electrode and the second transparent electrode are electrically insulated from each other and together form a first storage capacitor through the first insulating film, and the second transparent electrode and the third transparent electrode are electrically insulated from each other and together form a second storage capacitor through the second insulating film.
