摘要： A color conversion element includes a base substrate, and a first color filter layer, a second color conversion layer, and a third color conversion layer disposed on the base substrate, wherein the first color filter layer, the second color conversion layer, and the third color conversion layer are sequentially arranged on a plane, and wherein an interval between the first color filter layer and the second color conversion layer or an interval between the first color filter layer and the third color conversion layer is different from an interval between the second color conversion layer and the third color conversion layer.

摘要： There is provided a flat panel display device and a method of manufacturing the same. A flexible and transparent material is coated on a supporting substrate to a small thickness so that film substrates are easily formed. Step differences are formed in the film substrates so that a distance between pads of the two film substrates is reduced. Since conductive balls with reduced diameters are used so that the pads may be electrically connected, the distance between pads is reduced so that it is possible to easily miniaturize a high resolution flat panel display device, to prevent electrical connection defect between the pads, and to reduce manufacturing expenses.
