The invention relates to a liquid crystal display device with high aperture ratio, high transmittance and wide viewing angle, and a manufaturing method thereof. The liquid crystal display device includes a first substrate and a second substrate which are provided oppositely to each other, separated from each other with a certain distance, and in which a plurality of pixels are defined. A first alignment structure is overlaied on an interior surface of the first substrate. A second alignment structure is overlaied on an exterior surface of the second substrate. A liquid crystal layer is sandwiched between the first alignment structure and the second alignment structure. A first group of electrodes are formed on the interior surface of one of the first and the second substrates. A second group of electrodes are formed on the same surface where the first group of electrodes are located. A substantially fringing electric field is formed in a region above and below the first and second group of electrodes. A substantially horizontal electric field is formed in the regions of the liquid crystal layer between the first and second group of electrodes. The liquid crystal layer is treated so that liquid crystal molecules are aligned parallel to the surfaces of the first and second substrate in the absence of applied electric fields.
