Display substrate and display panel having the same

A display substrate, comprising:

• a base substrate configured to receive external light;
• an insulating layer disposed below the base substrate and having a first refractive index, wherein the insulating layer has an inherent reflective spectrum;
• a pixel electrode disposed below the insulating layer and having a second refractive index;
• and
• a first compensation layer disposed between the insulating layer and the pixel electrode, wherein an interface is defined between the insulating layer and the first compensation layer,
• wherein the first compensation layer has a third refractive index greater than the first refractive index and less than the second refractive index,
• wherein the interface is configured to reflect a portion of the external light, wherein the light reflected from the interface has a reflective spectrum, and wherein the first compensation layer is configured to modify the inherent reflective spectrum of the insulating layer to generate the reflective spectrum of the reflected light.

A display panel, comprising:

• a first display substrate configured to receive external light;
• and
• a second display substrate facing the first display substrate,
• wherein the first display substrate comprises:
• a first base substrate having a first refractive index and configured to receive the external light;
• a first insulating layer disposed below the first base substrate and having a second refractive index different from the first refractive index, wherein the first insulating layer has an inherent reflective spectrum;
• a first electrode disposed below the first insulating layer;
• and
• a first compensation layer, wherein an interface is defined between the first insulating layer and the first compensation layer,
• wherein the first compensation layer has a third refractive index greater than the first refractive index and less than the second refractive index,
• wherein the interface is configured to reflect a portion of the external light, wherein the light reflected from the interface has a reflective spectrum, and wherein the first compensation layer is configured to modify the inherent reflective spectrum of the first insulating layer to generate the reflective spectrum of the reflected light.
