It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The embodiment of the invention provides a display device which comprises a display panel. Referring to fig. 1, fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the present invention. The display panel 1 includes an array substrate 11 and a color film substrate 12.
The array substrate 11 includes a first substrate 111, a thin film transistor layer 112, a planarization layer 113, a metal layer 114, a first insulating layer 115, and a first electrode layer 116. The first substrate 11 is used for carrying a thin film transistor layer 112, a planarization layer 113, and other structures thereon.
Thin-film-transistor layer 112 is disposed on first substrate 11. As shown in fig. 1, the thin film transistor layer 112 includes an active layer 1121, a third insulating layer 1122, a gate layer 1123, a fourth insulating layer 1124, and a source drain layer 1125, which are sequentially stacked. The third insulating layer 1122 serves to insulate the active layer 1121 from the gate layer 1123, and the fourth insulating layer 1124 serves to insulate the gate layer 1123 from the source-drain layer 1125. The gate layer 1123 includes a gate. The source drain layer 1125 includes a source and a drain. The active layer 1121 is made of a polysilicon material, and specifically includes low-temperature polysilicon and high-temperature polysilicon. When the active layer 1121 is made of low temperature polysilicon, since the silicon crystal arrangement in the low temperature polysilicon is more ordered than that of amorphous silicon, the electron mobility becomes high. Further, the peripheral driver circuit can be formed on the first substrate 11, which can save space.
Through holes are formed in the third insulating layer 1122 and the fourth insulating layer 1124, and the source/drain layer 1125 and the active layer 1121 may be electrically connected by filling conductive material in the through holes.
The metal layer 114 is disposed on the planarization layer 113. The metal layer 114 includes a first metal portion 1141 and a second metal portion 1142, and the first metal portion 1141 and the second metal portion 1142 are spaced apart from each other. When the display panel 1 is a large-sized display panel, the metal layer 114 can be used to balance the resistance of the medium-sized display panel.
In one embodiment, as shown in fig. 2, the first metal portion 1141 and the second metal portion 1142 are both strip-shaped. In an embodiment, as shown in fig. 3, the first metal portion 1141 and the second metal portion 1142 are both arc-shaped, and the first metal portion 1141 and the second metal portion 1142 are connected to each other at their ends to form a circular metal layer.
The metal layer 114 is composed of one or more of Mo, Ni, Cr, Al, and Ag.
In an embodiment, the metal layer 114 is a film stack structure, and as shown in fig. 4, the metal layer 14 includes a first metal layer 1143, a second metal layer 1144, and a third metal layer 1145. A first metal layer 1143 is disposed on the planarization layer 113, a second metal layer 1144 is disposed on the first metal layer 1143, and a third metal layer 1145 is disposed on the second metal layer 1144.
In one embodiment, the composition material of the first metal layer 1143 is molybdenum, the composition material of the second metal layer 1144 is nickel, and the composition material of the third metal layer 1145 is molybdenum.
In one embodiment, the first metal layer 1143 is made of nickel, the second metal layer 1144 is made of aluminum, and the third metal layer 1145 is made of nickel.
In one embodiment, the composition material of the first metal layer 1143 is chromium, the composition material of the second metal layer 1144 is silver, and the composition material of the third metal layer 1145 is chromium.
In summary, as shown in fig. 4, the height H1 of the first metal layer 1143 ranges from 350 to 450 angstroms, and the width W1 ranges from 2 to 5 microns. The height H2 of the second metal layer 1144 ranges from 2500 to 3500 angstroms, and the width W2 of the second metal layer 1144 ranges from 2 to 5 microns. The height H3 of the third metal layer 1145 ranges between 350 and 450 angstroms and the width W2 ranges between 2 and 5 microns.
A first insulating layer 115 is disposed on the planarization layer 113 and the metal layer 114. Specifically, an insulating material is deposited on the planarization layer 113 and the metal layer 114, forming the first insulating layer 15. Since the first metal layer 114 has the first metal portion 1141 and the second metal portion 1142 in a convex shape, the first insulating layer 115 also forms a first bump 1151 disposed opposite to the first metal portion 1141 and a second bump 1152 disposed opposite to the second metal portion 1142.
In one embodiment, as shown in fig. 1 or 5, the array substrate 11 further includes a first electrode layer 116. The first electrode layer 116 is provided on a side of the first projection 1151 away from the second projection 1152.
In one embodiment, the array substrate 11 further includes a second insulating layer 117 and a third electrode layer 118, and the second insulating layer 117 is disposed on the first electrode layer 116 and the first insulating layer 115. Since first insulating layer 115 has second convex portion 1152 and first convex portion 1151 in a convex shape, when an insulating material is deposited on first insulating layer 115, second insulating layer 117 is formed to also have third convex portion 1171 disposed opposite to second convex portion 1152 and to have fourth convex portion 1172 disposed opposite to first convex portion 1151.
The third electrode layer 118 is disposed on a side of the third boss 1171 away from the fourth boss 1172, and is disposed on a side of the fourth boss 1172 away from the third boss 1171. The third electrode layer 118 and the first electrode layer 116 together control the bias of the liquid crystal molecules in the display panel 1, so that the display panel 1 realizes display. In this case, the liquid crystal molecules in the display panel 1 are aligned in a horizontal alignment manner, and when an external force is applied, the liquid crystal molecules slightly sink downward in structure, but the entire liquid crystal molecules are not affected in a horizontal shape, and thus, the liquid crystal molecules have high robustness and stability.
Through holes are formed in the planarization layer 113, the first insulating layer 115, and the second insulating layer 117, and the third electrode layer 118 can be electrically connected to the source/drain electrode layer 1125 by disposing a conductive material in the through holes.
In one embodiment, the array substrate 11 further includes a light-shielding layer 119 and a fifth insulating layer 120. The light-shielding layer 119 is disposed on the first substrate 111 for shielding light. The fifth insulating layer is disposed between the light-shielding layer 119 and the thin film transistor layer 112. As shown in fig. 1, a fifth insulating layer is provided between the light-shielding layer 119 and the active layer 1121.
The color filter substrate 12 includes a second substrate 121 and a supporting pillar 122. Wherein, one end of the supporting column 122 is disposed on the second substrate 121. As shown in fig. 5, when the array substrate 11 includes the third electrode layer 118, the other end of the support pillar 122 is defined at a recess between the third boss 1171 and the fourth boss 1172.
In an embodiment, as shown in fig. 1, when the color filter substrate 12 further includes a second electrode layer 123, and the second electrode layer 123 is disposed between the second substrate 121 and the supporting pillar 122, one end of the supporting pillar 122 is disposed on the second substrate 121, and the other end of the supporting pillar 122 is defined in a recess between the first protruding portion 1151 and the second protruding portion 1152. The second electrode layer 123 and the first electrode layer 116 constitute upper and lower electrodes for controlling the liquid crystal molecules in the display panel 1 to be biased.
In an embodiment, as shown in fig. 1 or 5, the color filter substrate 12 further includes a plurality of black matrixes 124 and a plurality of filter units 125. Among them, the black matrix 124 and the filter unit 125 are disposed on the second substrate 121, and the black matrix 124 is disposed between the adjacent filter units 125. When the color filter substrate 12 includes the second electrode layer 123, the second electrode layer 123 is disposed on the black matrix 124 and the filter unit 124. When the color filter substrate 12 does not include the second electrode layer 123, one end of the supporting pillar 122 is disposed on the black matrix 124.
In conclusion, one end of the supporting column 122 is limited in the concave, so that the supporting column 122 can be prevented from sliding into the through hole, the supporting column 122 is prevented from damaging other parts, and the yield of the display panel 1 is improved.
According to the display panel and the display device provided by the embodiment of the invention, the metal layers are arranged, so that the first insulating layers on the first metal part and the second metal part are upwards protruded to form the concave parts, and one ends of the supporting columns are limited on the concave parts, so that the supporting columns can be prevented from sliding, and the yield of the display panel is improved. Further, the metal layer may balance the resistance of the display panel and increase the signal strength of the second electrode or the third electrode.
In summary, although the present invention has been described with reference to the preferred embodiments, the above-described preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, therefore, the scope of the present invention shall be determined by the appended claims.
