Abstract: A display panel includes a first substrate including a display area, in which a plurality of pixel areas is arranged, and a non-display area around the display area, a second substrate disposed opposite to the first substrate, a light emitting array disposed on the first substrate and including a plurality of light emitting elements corresponding to the plurality of pixel areas, a sealing layer disposed in the non-display area between the first substrate and the second substrate and bonding the first substrate and the second substrate to each other, a vacuum layer sealed by the sealing layer and defined between the light emitting array and the second substrate, and a reflection adjustment layer disposed on the second substrate and absorbing a portion of external light, where the reflection adjustment layer includes a plurality of protrusions protruding toward the light emitting array and exposed to the vacuum layer.

Abstract: A cathode ray tube includes a panel having an inner surface and an outer surface and a funnel connected to the panel having a neck portion dimensioned to house an electron gun. A single strip of synthetic resin material is coated on a predetermined area of the panel. The synthetic resin includes intaglio in the form of a bar code. The heat-resistant synthetic resin material consists of silicone rubber or consists essentially of a silicone-modified vinyl resin and aluminum. The bar code is undamaged by heat, even during a heating process of several steps, e.g., a baking process, so that the bar code and sheet can be formed during the initial steps of manufacturing the cathode ray tube. Accordingly, since the bar code is present throughout the CRT's manufacture, product management can be done all along the assembly line.
