An electronic display panel comprising a plastic substrate; a bottom shield metal (BSM) on the plastic substrate; a thin-film transistor (TFT) on the BSM, the TFT and the BSM at least partially overlapping each other; and an active buffer layer between the TFT and the BSM, wherein the BSM is connected to one of a gate electrode, a source electrode, and a drain electrode of the TFT. A bottom shield metal (BSM) on the plastic substrate, the BSM located to minimize formation of a back channel in a pixel circuit by trapped charges of the plastic substrate, the pixel circuit in a pixel area defined by a gate line and a data line on the plastic substrate, the pixel circuit on the active buffer layer including a plurality of TFTs and a plurality of component interconnecting nodes.

Thin film transistor substrate, display panel including the same, and method of manufacturing the same

An electrophoretic display (EPD) device adapted to prevent a dispensed fluid sealant from moving toward a non-active area is disclosed. The EPD device includes: a first substrate configured to include a flexible plate divided into an active area and a non-active area; a thin film transistor array formed on the active area of the plate; a second substrate opposite to the first substrate; an electrophoretic film, between the first and second substrates, configured to contain charged particles driven depending on electrophoresis; a sealant, between the first and second substrates, hardened from fluid state; a sealant block formed on a sealant formation region to prevent the fluid sealant from flowing into the non-active area before hardening of the fluid sealant, wherein the sealant block is configured to include a first dam, a second dam, and a furrow between the first and second dams.
