a second substrate facing the first substrate;
an organic light emitting element arranged within the emission region of the first substrate;
a sealing member arranged within the peripheral region of the first substrate and configured to bond together the first substrate and the second substrate upon being cured by a laser beam;
a sensing cell arranged on the second substrate at a location that corresponds to organic light emitting element;
a conductive pattern arranged on the second substrate at a location that corresponds to the circuit region;
a block pattern arranged on the second substrate at locations that correspond to the sealing member; and
a protective layer covering the sensing cell, the conductive pattern, and the block pattern on the second substrate,wherein the block pattern and the conductive pattern are comprised of a same material selected from a group consisting of molybdenum, silver, titanium, copper, aluminum, molybdenum/aluminum/molybdenum, andwherein the sensing cell is comprised of a material selected from a group consisting of indium tin oxide, indium oxide, indium zinc oxide, tin oxide, zinc oxide.

Abstract
An organic light emitting display (OLED) device that includes a first substrate and a second substrate. An organic light emitting element and a sealing member are formed between the first substrate and the second substrate. A touch panel, a block pattern, and a protective layer are formed on the second substrate. The block pattern is arranged above the sealing member to prevent a center of the sealing member from being excessively illuminated by a laser beam during a curing process.

11. A method of manufacturing an organic light emitting display (OLED) device, comprising:
-
preparing a first substrate that includes an emission region, a peripheral region that surrounds a circuit region, the circuit region being arranged between the emission region and the peripheral region, the peripheral, region being spaced apart from the emission region by the circuit region; forming an organic light emitting element within the emission region of the first substrate; forming a sealing member within the peripheral region of the first substrate on all four sides of the emission region; preparing a second substrate; forming a sensing cell on the second substrate at a location that corresponds to organic light emitting element; forming a conductive pattern on the second substrate at a location that corresponds to the circuit region; forming a block, pattern on the second substrate at a location that corresponds to the sealing, member on all four sides of the emission region; forming a protective layer on the second substrate to cover the sensing, cell, the conductive patter, and the block pattern; arranging the second substrate to face the first substrate; and bonding together the first substrate and the second substrate by illuminating a laser beam onto the sealing member, the block pattern to provide for a more uniform heat distribution across a width of the sealing member during the bonding by being interposed between a laser source of the laser beam and the sealing member and by blocking a portion of the laser beam that corresponds to the central axes of the sealing member, wherein the block pattern and the conductive pattern are comprised of a same material selected from a group consisting of molybdenum, silver, titanium, copper, aluminum, molybdenum/aluminum/molybdenum, wherein the sensing cells are comprised of a material selected from a group consisting of indium tin oxide, indium oxide, indium zinc oxide, tin oxide, zinc oxide. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
