[0032] Please refer Figure 2 to Figure 5 The first embodiment of the present invention provides a display panel 20 including a first substrate 21, a second substrate 22 disposed opposite to the first substrate 21, and a liquid crystal layer 23 located between the first substrate 21 and the second substrate 22.

[0033] The first substrate 21 may be a thin film transistor array substrate. The first substrate 21 is provided with multiple scan lines (not shown), multiple data lines (not shown), and multiple One thin film transistor T, a common electrode 216 and a plurality of pixel electrodes 218. The plurality of scan lines and the plurality of data lines are insulated and crossed to define a plurality of pixel regions SP arranged in an array ( Figure 2 to Figure 5 Indicates one of the pixel regions SP). Each pixel region SP is provided with a thin film transistor T and a pixel electrode 218, and the pixel electrode 218 is connected to a corresponding scan line and a data line th...

[0055] Please refer Figure 6 to Figure 9 The second embodiment of the present invention provides a display panel 20 including a first substrate 21, a second substrate 22 disposed opposite to the first substrate 21, and a liquid crystal layer 23 located between the first substrate 21 and the second substrate 22. The first substrate 21 may be a thin film transistor array substrate, and the second substrate 22 may be a color filter substrate.

[0056] The main difference between this embodiment and the above-mentioned first embodiment is that the pixel electrode 218 and the common electrode 216 are respectively located on different substrates. The pixel electrode 218 is formed on the first substrate 21 and the common electrode 216 is formed on the second substrate 22. For other structures of this embodiment, reference may be made to the above-mentioned first embodiment, which will not be repeated here.

Abstract

A display panel (20) and a display device. The display panel (20) comprises a first substrate (21), a second substrate (22) and a liquid crystal layer (23) located between the first substrate (21) andthe second substrate (22). A plurality of pixel regions (SP) are formed on the first substrate (21). The liquid crystal layer (23) contains liquid crystal molecules (231). A first alignment layer (219) is arranged on the first substrate (21) and is close to the liquid crystal layer (23); a second alignment layer (224) is arranged on the second substrate (22) and is close to the liquid crystal layer (23); a polarizing plate (223) is arranged on the outer side of the second substrate (22); the polarizing plate (223) has a light-transmitting axis (P1). The first alignment direction (X1) of the first alignment layer (219) and the second alignment direction (X2) of the second alignment layer (224) are reversely parallel; the light guide plates are perpendicular to the direction of a light transmission axis (P1) of the polarizing plate (223); quantum rods (232) are doped in the liquid crystal layer (23); in each pixel region (SP), the quantum rods (232) with different sizes are mixed with the liquid crystal molecules (231); the liquid crystal molecules (231) are arranged in the first alignment direction (X1) and the second alignment direction (X2), the arrangement direction of the quantum rods (232) is consistent with that of the liquid crystal molecules (231), and the quantum rods (232) can convert incident non-polarized light into linearly polarized light with the same long axis direction.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device having the display panel. Background technique [0002] Liquid crystal display panels (LCDs) have the advantages of good image quality, small size, light weight, low driving voltage, low power consumption, no radiation, and relatively low manufacturing costs, and are dominant in the field of flat panel displays. [0003] Such as figure 1 As shown, figure 1 It is a schematic cross-sectional view of an existing typical liquid crystal display device. The liquid crystal display device includes a display panel 40 and a backlight unit 50. The display panel 40 includes an array substrate 41, a color filter substrate 42 and a liquid crystal layer 43 sandwiched between the array substrate 41 and the color filter substrate 42. An upper polarizer 44 is provided above the color filter substrate 42 A lower polarizing plate 45 is provided under the array...
