Organic light-emitting display device

An organic light-emitting display device comprising:

• a first substrate;
• a second substrate disposed to face the first substrate;
• a display unit interposed between the first substrate and the second substrate and comprising an organic light-emitting device;
• a sealing member disposed to surround the display unit between the first substrate and the second substrate and that bonds the first substrate to the second substrate;
• and
• a filler disposed in a space defined by the first and second substrates and the sealing member to cover the display unit, the filler comprising:
• a first photochromic material comprising a compound absorbing light in a wavelength of about 470 nm to about 490 nm and represented by Formula 1;
• and
• a second photochromic material absorbing light in a wavelength of about 550 nm to about 580 nm and represented by Formula 1:
• wherein R1, R2, R3, R4, R5, and R6 are each independently hydrogen, heavy hydrogen, or halogen, and Ar1 and Ar2 are each independently a group below;
• Y represents O, S, SO, or SO2;
• X represents C or N;
• * represents a bond;
• R8 represents a C1 to C50 alkyl group or a C5 to C60 aryl group;
• and
• R7 and R9 are each independently an unshared electron pair, hydrogen, heavy hydrogen, or a C1 to C50 alkyl group;
• wherein an amount of the photochromic material of the filler is in the range of about 50 to about 70 parts by weight based on 100 parts by weight of the filler.
