Embodiment 1

[0128] By pad printing in ITO A composition comprising bisphenol A epoxy resin is patterned on the substrate. The epoxy pattern is hardened to form a plurality of polymer patterns. Next, a silver paste containing 80% by weight of silver nanoparticles and 20% by weight of epoxy-based curable resin was prepared. Silver paste was patterned on each polymer pattern by pad printing method. Next, the patterned silver paste is heat-treated to form silver wiring. Next, a protective layer composition containing a black material and an epoxy resin was prepared. A protective layer composition is applied and allowed to harden to cover multiple polymer patterns and silver wiring to produce a Figure 8 A sample of the same structure as shown in . (The width of the polymer pattern is 60 μm, the interval between the polymer patterns is 20 μm, the width of the silver wiring is 50 μm, and the interval between the wiring is 30 μm)

Embodiment 2

[0130] In Example 2, the formation of the protective layer was omitted, and a polymer pattern and silver wiring were formed on the substrate by the same method as in Example 1.

Abstract

The invention relates to a display device and a multi-panel display device. A display device according to an exemplary embodiment of the present disclosure includes a plurality of signal lines disposed on an upper surface of a first substrate and electrically connected to a display unit, a plurality of connection lines disposed below the first substrate, a plurality of polymer patterns disposed on a side surface of the first substrate and connecting each of the signal lines and each of the connection lines to each other, and a plurality of side lines electrically connecting the plurality of signal lines and the plurality of connection lines and disposed on the plurality of polymer patterns to overlap each of the polymer patterns. According to an exemplary embodiment of the present disclosure, a bezel region is narrower and includes a polymer pattern to suppress migration of a metal component generated in a side line and improve an adhesive force of the side line. By doing so, the reliability of the display device is improved and a wiring pattern having a narrow pitch may be formed.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2020-0125518 filed with the Korean Intellectual Property Office on September 28, 2020, the disclosure of which is incorporated herein by reference. technical field [0003] The present disclosure relates to a display device and a multi-panel display device, and more particularly, to a display device and a multi-panel display device capable of realizing a narrow bezel with high reliability by delaying migration of metal parts generated in side lines. Background technique [0004] In general, a display device includes a display panel having a display area in which an image is displayed and a non-display area defined along the periphery of the display area, a plurality of driving circuits provided in the non-display area, and supplying control signals to the plurality of driving circuits printed circuit board (PCB). A plurality of connection lines con...
