Abstract: A near-to-eye display device and wearable apparatus are provided. The near-to-eye display device includes: pixel islands and micro-lenses in one-to-one correspondence with the pixel islands; wherein each pixel island emits light to a corresponding micro-lens so that the light reaches a predetermined viewing position after passing through the corresponding micro-lens. The near-to-eye display device further includes: super-lens units each including at least one super-lens; wherein the super-lens units are in one-to-one correspondence with the pixel islands; each super-lens unit is on a side of a corresponding pixel island proximal to the corresponding micro-lens, and an orthogonal projection of the super-lens unit on a plane where the corresponding pixel island is located covers the corresponding pixel island. The super-lens unit converges light, which is within a predetermined angle, emitted by the corresponding pixel island, to reduce a diffusion angle of the light emitted by the corresponding pixel island.
