Array substrate and display panel comprising light adjusting layer between transparent layers

An array substrate, comprising:

• at least two transparent layers stacked in sequence, wherein in the at least two transparent layers, a light adjusting layer is arranged between at least adjacent two of the transparent layers,
• wherein a product of a refractive index of the light adjusting layer and a thickness of the light adjusting layer is greater than one half of a preset wave train length to avoid forming Newton's ring, the preset wave train length refers to a wave train length of a preset-wavelength light incident into the array substrate;
• wherein the light adjusting layer comprises a first light modulation layer, an optical path adjustment layer and a second light modulation layer stacked in sequence, two sides of the optical path adjustment layer are respectively attached to the first light modulation layer and the second light modulation layer;
• a refractive index of the first light modulation layer is between a refractive index of a transparent layer adjacent to the first light modulation layer and a refractive index of the optical path adjustment layer;
• a refractive index of the second light modulation layer is between a refractive index of a transparent layer adjacent to the second light modulation layer and the refractive index of the optical path adjustment layer;
• and a product of the refractive index of the optical path adjustment layer and a thickness of the optical path adjustment layer is greater than one half of the preset wave train length;
• wherein the array substrate comprises a substrate and a buffer layer, and the buffer layer comprises a first buffer layer close to the substrate and a second buffer layer parallel to and opposite to the first buffer layer;
• and
• the light adjusting layer is arranged between the first buffer layer and the second buffer layer, and both sides of the light adjusting layer located between the first buffer layer and the second buffer layer are respectively attached to the first buffer layer and the second buffer layer.
