Touch screen display apparatus and method of manufacturing the same

A touch screen display apparatus comprising:

• a first substrate;
• a pixel electrode and a lower sensor electrode which are each disposed on the first substrate;
• a second substrate which faces the first substrate;
• a common electrode which is disposed on the second substrate and overlaps the pixel electrode;
• an upper sensor electrode which is disposed on the second substrate and faces the lower sensor electrode;
• a liquid crystal layer which comprises liquid crystal molecules interposed between the first substrate and the second substrate;
• a first alignment layer which is disposed on the pixel electrode and the common electrode;
• a second alignment layer which is disposed on the lower sensor electrode;
• and
• a third alignment layer which is disposed on the upper sensor electrode,
• wherein
• at least one of the second and third alignment layers aligns the liquid crystal molecules in a different direction from a direction in which the first alignment layer aligns the liquid crystal molecules,
• when touch pressure is applied onto a point on the first or second substrate, a distance between the lower sensor electrode and the upper sensor electrode at the point is changed, and
• a position of the point is detected by using a change in capacitance between the lower sensor electrode and the upper sensor electrode according to the change in the distance between the lower sensor electrode and the upper sensor electrode.
