摘要： A liquid crystal display device comprises an array substrate having first and second pixel electrodes arranged adjacent each other and a counter substrate having a counter electrode opposing to the first and second pixel electrodes. First and second slits are formed on the counter electrode opposing to the first and second pixel electrode so as to cross the first and second pixel electrode, respectively. The counter electrode is separated into a first counter electrode portion and a second counter electrode portion by the first and second slits. A connecting counter electrode portion is arranged between the first and second slits to connect the first and second counter electrode portions. A columnar spacer is arranged between the first and second slits opposing to the connecting counter electrode portion to form a cell gap between the array substrate and the counter substrate.
