Abstract
Provided is a display panel comprised of a white color organic luminescent element and a color filter for full color implementation, wherein a substrate in which an organic luminescent element is formed and a color filter are assembled and fixed to face each other with an adhesive pattern therebetween, and liquid oil is filled between the color filter and the substrate inside of the adhesive pattern so as to block external moisture or oxygen, so that deterioration of luminous characteristics due to the external moisture or oxygen may be prevented by encapsulating the organic luminescent element and the color filter with the liquid oil, which leads to enhance reliability and stability of the element, and also allows the encapsulation process to be performed with relatively simple steps and low cost.
