Problems solved by technology

[0006] For passive array display and active matrix display driven by thin film transistors, due to the existence of signal lines, driving lines and thin film transistors, after the light from the side light source enters the liquid crystal cell, it will be reflected by the metal layer, or the metal layer and the upper electrode The overlapping area scatters light and causes a decrease in display contrast, which affects the display effect

Embodiment 1

[0033] combine Figure 1-3 As shown, the present embodiment provides a display substrate, which is particularly suitable for use in transparent display devices (ie, optical waveguide displays). The display substrate of this embodiment specifically includes: a base 10, and a reflective structure 1 located on the base 10; wherein, the reflective structure 1 has a bottom surface located on the base 10, a top surface opposite to the bottom surface, and a side surface connecting the bottom surface and the top surface. . In particular, at least one first film group is provided between the bottom surface of the reflective structure 1 of the display substrate of this embodiment and the substrate 10; Film group; each first film group includes a first functional layer 2 and a second functional layer 3 arranged in sequence along the direction away from the substrate 10; the orthographic projection of the first functional layer 2 and the second functional layer 3 on the substrate 10 is a...

Embodiment 2

[0048] This embodiment provides a display device, which includes a first substrate and a second substrate oppositely arranged; wherein, at least one of the first substrate and the second substrate adopts the display substrate in Embodiment 1; the display device is preferably Transparent display device. The first substrate and the second substrate are oppositely arranged to form a liquid crystal cell 6, and liquid crystal molecules are poured into the liquid crystal cell 6; the liquid crystal molecules include polymer stabilized liquid crystals.

[0049] Specifically, such as Figure 4 As shown, taking the first substrate as the display substrate in Embodiment 1 as an example; wherein, the reflective structure 1 is a metal conductive structure (such as a grid line), so a black matrix is ​​provided on the second substrate at a position corresponding to the reflective structure 1 7. To prevent the liquid crystal molecules at the position of the reflective structure 1 from deflec...

Abstract

The invention provides a display substrate and display device, and belongs to the technical field of display. The display substrate comprises a substrate, and a reflection structure arranged on the substrate; the reflection structure is provided with a bottom surface arranged on the substrate, a top surface opposite to the bottom surface and a side surface connected with the top surface and the bottom surface; at least one first film group is arranged between the bottom surface of the reflection structure and the substrate; the first film group comprises a first functional layer and a second functional layer which are sequentially arranged along the direction, away from the substrate; the forward projections of the first functional layer and the second functional layer on the substrate areat least coincident with the forward projection of the bottom surface of the reflection structure on the substrate; the refractive index of the first functional layer is smaller than the refractive index of the second functional layer; and / or at least one second film group are arranged on the peripheral region of the side surface of the reflection structure and the top surface of the reflection structure; the second film group comprises a third functional layer and a fourth functional layer which are sequentially covered along the direction, away from the substrate; the fourth functional layer has a refractive index less than the refractive index of the third functional layer.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display substrate and a display device. Background technique [0002] Transparent display has attracted the attention of consumers with its cool transparent features, but it can only be seen in sci-fi movies in the early days. With the development of technology, transparent display gradually enters people's life. Transparent displays are expected to be widely used in daily life: such as transparent refrigerators, transparent computer monitors, transparent windows, traffic signs, etc., with broad application prospects. [0003] However, in the prior art, such as liquid crystal display and organic semiconductor light-emitting diode display, the transmittance is low when performing transparent display, and the transmittance of liquid crystal display is generally below 10%. [0004] OLED is generally below 40%; polymer dispersed liquid crystal display, electrochromic...
