Abstract
In an active matrix type liquid crystal display device in which a common electrode and a second pixel electrode have portions opposing each other, and an electric field parallel to substrates is formed between the two electrodes, Y direction extending portions of the common electrode are provided above data lines via a second interlayer insulation film. Slits are opened in the Y direction extending portions of the common electrode along the data lines. Portions of a black matrix which are set to a common electric potential with the common electrode are provided on an opposing substrate at positions opposing the slits.
