Claim 0:
1. A transparent display device, comprising:
a substrate provided thereon with a display area and a non-display area adjacent to the display area, the display area including a transmissive area and a non-transmissive area;
a plurality of subpixels provided on the display area;
at least one inorganic insulating film on the substrate;
at least one organic insulating film on the at least one inorganic insulating film;
anode electrodes provided in each of the plurality of subpixels on the at least one organic insulating film;
a bank provided among the anode electrodes;
a light emitting layer on the anode electrodes;
a cathode electrode on the light emitting layer;
an encapsulation film on the cathode electrode;
at least two color filters provided over the encapsulation film, each of the color filters overlapping at least part of the bank;
an adhesive layer provided between the at least two color filters, the adhesive layer adjoining a side surface of each of the at least two color filters; and
a step difference compensation film positioned between the encapsulation film and the cathode electrode in the transmissive area,
wherein the step difference compensation film is made of a material different from that of the at least one organic insulating film, and the step difference compensation film includes a transparent polyimide,
wherein the adhesive layer is provided in the transmissive area and is made of a transparent material,
wherein the at least one organic insulating film includes a first planarization film on the at least one inorganic insulating film and a second planarization film on the first planarization film, and
wherein the at least one inorganic insulating film, the first planarization film, the second planarization film, and the bank are provided in only the non-transmissive area.
