1. A display module comprising:
a first substrate comprising a red filter, a green filter, a blue filter, and a white filter; a second substrate disposed facing the first substrate and comprising:
a first switching device and a first transparent electrode being formed corresponding to a position where the red filter is disposed, the center of the red filter and the center of the first transparent electrode being aligned along a first vertical axis,a second switching device and a second transparent electrode being formed corresponding to a position where the green filter is disposed, the center of the green filter and the center of the second transparent electrode being aligned along a second vertical axis,a third switching device and a third transparent electrode being formed corresponding to a position where the blue filter is disposed, the center of the blue filter and the center of the third transparent electrode being aligned along a third vertical axis, anda fourth switching device and a reflective part being formed corresponding to a position where the white filter is disposed, the center of the white filter and the center of the reflective part being aligned along a fourth vertical axis; and a liquid crystal layer formed between the first substrate and the second substrate, wherein light incident from an outside is directly provided at the fourth switching device, wherein the first switching device is formed on an intersection area of a gate line and a first sub-pixel data line, the second switching device is formed on an intersection area of the gate line and a second sub-pixel data line, the third switching device is formed on an intersection area of the gate line and a third sub-pixel data line, the fourth switching device is formed on an intersection area of the gate line and a fourth sub-pixel data line, wherein the reflective part is formed with a size corresponding to an area of the white filter, such that the reflective part prevents the light incident from the bottom of the white filter from transmitting through the white filter, wherein the first, second, and third transparent electrodes are formed in a same horizontal plane in the second substrate as the reflective part, wherein a size of the fourth sub-pixel area in which the fourth switching device and fourth sub-pixel data line are formed is smaller than a size of each of the first sub-pixel area in which the first switching device and first sub-pixel data line are formed, the second sub-pixel area in which the second switching device and second sub-pixel data line are formed, and the third sub-pixel area in which the third switching device and third sub-pixel data line are formed, and wherein a size of the white filter is smaller than a size of each of the red filter, the green filter, and the blue filter, and wherein the reflective part includes a first reflective part formed of a same material as a gate electrode constituting the fourth switching device, the first reflective part being formed on the same layer as the gate electrode constituting the fourth switching device, and the reflective part includes a second reflective part formed of a same material as a drain electrode constituting the fourth switching device, the second reflective part being formed on a same layer as the drain electrode constituting the fourth switching device.
