Thin-film-transistor　liquid-crystal　displays　(TFT-LCDs)　have　gained　popularity　due　to　their　widespread　use　in　the　production　of　televisions,　laptops,　and　iPads.　TFT-LCD　firms＇　activities　that　build　relationships　with　suppliers　and　customers　contribute　to　the　emergence　of　supply　networks.　A　firm＇s　ability　to　identify　risks,　however,　is　complicated,　as　TFT-LCD　supply　networks　are　becoming　increasingly　global,　complex,　and　interconnected.　The　extant　research　on　the　topological　structure　of　TFT-LCD　supply　networks　is　limited,　and　the　risks　identified　rely　on　untested　assumptions　about　the　topological　structure　of　such　networks.　To　fill　these　gaps,　this　study　examines　the　topological　structure　and　COVID-19　related　risk　propagation　in　TFT-LCD　supply　networks　from　a　dynamic　perspective.　First,　the　evolution　of　the　topological　structure　of　TFT-LCD　supply　networks　from　2015　to　2020　is　explored　by　constructing　a　weighted　and　undirected　supply　network.　Second,　the　hidden　risky　sources　in　TFT-LCD　supply　networks　are　revealed　by　the　proposed　risk　propagation　model.　The　results　show　that　TFT-LCD　supply　networks　are　characterised　by　a　＇hub　and　spoke＇　feature　and　an　explicit　shift　from　geographical　to　global　cooperation.　Additionally,　a　＇robust-yet-fragile＇　configuration　in　these　supply　networks　is　uncovered,　and　the　hidden　risky　sources　in　the　main　TFT-LCD　manufacturers　and　suppliers　and　in　interfirm　cooperations　are　revealed.　These　findings　will　help　managers　reduce　the　vulnerability　of　TFT-LCD　supply　networks　to　disruptions　and　construct　more　robust　and　resilient　networks.
