ABSTRACT:
In an array substrate, an LCD panel having the same and an LCD device having the same, the array substrate may include an insulating substrate, a switching element (e.g., a transistor such as a TFT), a main pixel portion, a coupling capacitor and a sub-pixel portion. The switching element may be formed on the insulating substrate in a pixel region defined by gate and data lines adjacent to each other. The gate and data lines may be formed on the insulating substrate. The main pixel portion is on a first (e.g., central) portion of the pixel region. The coupling capacitor is electrically connected to the switching element. The coupling capacitor is on the insulating substrate. The sub-pixel portion is electrically connected to the coupling capacitor. The sub-pixel portion is on a second (e.g., peripheral) portion of the pixel region. Therefore, an image display quality is improved.
