Abstract
A substrate and a light-emitting substrate are provided. The substrate includes a driving function layer, an insulating layer, and a reflective layer which are sequentially arranged on a base. The driving function layer includes a conductive pad. An opening exposing the conductive pad is defined on the insulating layer. In a direction perpendicular to the substrate, a height of a part of the insulating layer located surrounding the opening is greater than a height of the reflective layer.
Claims20
A substrate, comprising:
- a base;
- a driving function layer located at a side of the base, wherein the driving function layer comprises a conductive pad;
- an insulating layer disposed on a side of the driving function layer away from the base, wherein an opening exposing the conductive pad is defined on the insulating layer;
- and
- a reflective layer disposed on a side of the insulating layer away from the base;
- wherein in a direction perpendicular to the substrate, a height of a part of the insulating layer located surrounding the opening is greater than a height of the reflective layer, the part of the insulating layer located surrounding the opening protrudes from a surface of the reflective layer on a side of the insulating layer away from the base, and
- wherein a part of the driving function layer protrudes in a direction facing away from the base.
A light-emitting substrate, comprising a substrate and a light-emitting diode (LED) chip disposed on the substrate;
- wherein the substrate comprises:
- a base;
- a driving function layer located at a side of the base, the driving function layer comprises a conductive pad;
- an insulating layer disposed on a side of the driving function layer away from the base, an opening exposing the conductive pad is defined on the insulating layer;
- and
- a reflective layer disposed on a side of the insulating layer away from the base;
- in a direction perpendicular to the substrate, a height of a part of the insulating layer located surrounding the opening is greater than a height of the reflective layer, the part of the insulating layer located surrounding the opening protrudes from a surface of the reflective layer on a side of the insulating layer away from the base, and
- wherein a part of the driving function layer protrudes in a direction facing away from the base.
