Patent ID: 7876387

Claim:
A lateral electric field type liquid crystal display device comprising: a first substrate and a second substrate placed opposite to each other at an approximately constant gap; a liquid crystal layer formed between the first substrate and the second substrate; drain bus lines formed on the first substrate; gate bus lines formed on the first substrate in such a way as to be intersected with the drain bus lines; pixel regions defined in a matrix array by the drain bus lines and the gate bus lines; at least one first liquid crystal driving electrode and second liquid crystal driving electrodes formed on the first substrate; thin-film transistors formed on the first substrate for the respective pixel regions; and storage capacitor electrodes formed on the first substrate for the respective pixel regions; wherein an alignment direction of liquid crystal molecules existing in the liquid crystal layer is rotated in planes approximately parallel to the first substrate and the second substrate by applying liquid crystal driving electric field to the liquid crystal layer using the at least one first liquid crystal driving electrode and the second liquid crystal driving electrodes, thereby displaying images; the drain bus lines are entirely covered with the at least one first liquid crystal driving electrode; the gate bus line corresponding to each of the pixel regions is covered with the at least one first liquid crystal driving electrode except for a predetermined non-overlapped area existing in a part that does not overlap with the corresponding thin-film transistor; and the predetermined non-overlapped area of the gate bus line corresponding to each of the pixel regions is covered with the storage capacitor electrode corresponding to the adjacent pixel region.
