Abstract
A substrate for a display apparatus includes a barrier layer disposed on a base substrate. The barrier layer includes a silicon oxide layer, and the silicon oxide layer includes a first part and a second part along a thickness direction of the barrier layer. The amount of silicon in the first part is different from the amount of silicon in the second part.
Claims18
A substrate for a display apparatus, the substrate comprising:
- a base substrate;
- and
- a barrier layer disposed on the base substrate, wherein the barrier layer includes a silicon oxide layer and the silicon oxide layer includes a first part and a second part along a thickness direction of the barrier layer, wherein an amount of silicon in the first part is different from an amount of silicon in the second part, wherein:
- the barrier layer includes a first barrier layer which includes the first part and a second barrier layer which includes the second part that contains a greater amount of silicon than the first barrier layer,
- the second barrier layer is distal to the substrate than the first barrier layer such that the first barrier layer is between the substrate and the second barrier layer, the first barrier layer being a barrier layer closest to the base substrate, and wherein a plurality of first and second barrier layers are alternately stacked on one another.
