According to an exemplary embodiment, the display device includes: a substrate that overlaps a light transmission area, a display area that surrounds the light transmission area, and a boundary area that is disposed between the light transmission area and the display area; a first light blocking member that is disposed on the substrate and overlaps the boundary area; a window that overlaps the substrate; and a second light blocking member that is disposed between the first light blocking member and the window, and overlaps the boundary area, wherein the first light blocking member includes a first opening that overlaps the light transmission area, the second light blocking member includes a second opening that overlaps the light transmission area, and a diameter of the first opening is larger than a diameter of the second opening.

A display module, a method of manufacturing the same, and a display device are provided. The display module comprises: a light guide plate; a blue light source, disposed at the light entering face of the light guide plate; and a display panel, disposed at a side of the light exiting face of the light guide plate, the display panel comprises a plurality of display units, and adjacent display units are spaced apart with a light shielding barrier wall; each display unit comprises a quantum dot unit and a liquid crystal unit arranged side by side, and the liquid crystal unit and the quantum dot unit are spaced apart with a transparent barrier wall; a side of the liquid crystal unit away from the light guide plate is provided with a first light shielding pattern.

A liquid-crystal display (LCD) device includes: an array substrate on which a sub-pixel is disposed; a color filter substrate on which a color filter corresponding to the sub-pixel is disposed; and a liquid-crystal layer between the array substrate and the color filter substrate. The array substrate comprises a lens hole, the color filter substrate comprises a lens hole guide, and a diameter of the lens hole is smaller than an inner diameter of the lens hole guide.

The present disclosure provides a liquid crystal display panel and a display device. The liquid crystal display panel includes an upper substrate and a lower substrate disposed opposite to the upper substrate. The lower substrate includes a non-display area having a connection terminal disposed therein. The connection terminal has an elongated stripe shape. By replacing the connection terminal having a square shape or a square-like shape with a connection terminal having an elongated stripe shape, light-reflection problems caused by metal having a large area in a local region are mitigated. Therefore, the technical problem that user experiences of using display devices are unsatisfactory because of light-reflection issues caused by conventional connection terminal is solved.

An active-pixel device assembly with stray-light reduction includes an active-pixel device including a semiconductor substrate and an array of active pixels, a light-transmissive substrate disposed on a light-receiving side of the active-pixel device, and a rough opaque coating disposed on a first surface of the light-transmissive substrate and forming an aperture aligned with the array of active pixels, wherein the rough opaque coating is rough so as to suppress reflection of light incident thereon from at least one side. A method for manufacturing a stray-light-reducing coating for an active-pixel device assembly includes depositing an opaque coating on a light-transmissive substrate such that the opaque coating forms a light-transmissive aperture, and roughening the opaque coating to form a rough opaque coating, said roughening including treating the opaque coating with an alkaline solution.

A display device is provided. The display device includes a display panel and a backlight module. The display panel includes sub-pixels and a light-shielding layer disposed around the sub-pixels. A reflective nano-grating is disposed on one side of the light-shielding layer near the backlight module. The backlight module provides a backlight source for the display panel, and the backlight source is converted into a polarized light in the display panel. The reflective nano-grating is used to reflect at least one part of the polarized light emitted toward the reflective nano-grating back to the backlight module for recycling.
