The opening ratio of each pixel at the first pixel row with the storage capacitor formed between the corresponding pixel electrode and the storage capacitor line differs from the opening ratio of the pixels at the other pixel rows. The difference in the opening ratio is made through forming a light interception pattern at each pixel of the first pixel row, or through differentiating opening areas of the black matrix. In order to prevent leakage of light, light interception patterns may be formed at the region between the display area and the pads.
