Liquid crystal display device

A liquid crystal display device, comprising:

• an array substrate including;
• a plurality of gate lies and source lines to form pixels in a matrix,
• a pixel electrode formed in each pixel and having a first pixel electrode portion extending in a first direction, and a second pixel electrode portion connected with the first pixel electrode portion and extending in the second direction orthogonally crossing the first direction,
• a switching transistor having a gate electrode connected to the gate line extending in the second direction, a source electrode connected to the source line extending in the first direction and a drain electrode connected with the pixel electrode,
• a counter substrate opposing to the array substrate and including a counter electrode having a first counter electrode portion arranged in parallel with the first pixel electrode portion;
• and
• a liquid crystal layer held between the first and second substrates,
• wherein a lateral electrical field generated between the first pixel electrode portion and the first counter electrode portion is applied to the liquid crystal layer.
