Abstract
A PDP has first and second substrates which face each other with a space in between. A display electrode pair and a dielectric layer are formed on the first substrate, and a plurality of discharge cells are formed between the first and second substrates along the display electrode pair. In this construction, two or more depressions are provided in the dielectric layer in an area corresponding to each discharge cell. This improves luminous intensity and illumination efficiency. Also, to form the dielectric layer on the first substrate, first a transfer film is made by providing a dielectric precursor layer on a support film, then depressions are formed in the dielectric precursor layer of the transfer film, and lastly the dielectric precursor layer of the transfer film is transferred onto the first substrate. This decreases the number of manufacturing steps and increases the yield, thereby reducing manufacturing costs.
