Abstract
Picture element electrodes (7) are electrically connected with drain electrodes (18D) of respective transistor elements (18). The picture element electrodes (7) and data signal lines (SLn, SLn+1, . . . ) are provided above scanning signal lines (GLn, GLn+1, . . . ). The picture element electrodes (7) overlap scanning signal lines (GLn, GLn+1, . . . ) when viewed from above. Notch parts 7a and 7b are provided in each picture element electrode (7) so as to overlap each of the scanning signal lines (GLn, GLn+1, . . . ). Shield electrodes (4a, 4b) are formed in the same layer as the data signal lines (SLn, SLn+1, . . . ). Each of the scanning signal lines (GLn, GLn+1, . . . ) at least partially overlaps the shield electrodes (4a, 4b) in the notch parts (7a, 7b), when viewed from above. This provides the liquid crystal display panel having wide viewing angle characteristic and carrying out high quality display.
