Abstract:
A flexible PCB(Printed circuit board) of a display panel is provided to implement high performance FPCB with thin, heat resistance, and gas-barrier properties by forming an evenness layer on the metal layer. An FPCB(100A) comprises a plastic layer having a glass fiber cloth(110), a metal layer(130) laminated on the plastic layer, and an evenness layer(140) laminated on the metal layer. The plastic layer is formed by precipitating the plastic fiber cloth in the plastic resin melt solution, and drying it. Since the plastic layer is made including the glass fiber cloth of which the coefficient of thermal expansion is small, it improves the connection reliability with the part connected to the top of the substrate. Preferably the thickness of the plastic layer is 10 ~ 300 mum, more proper range is 50 ~ 200 mum. The plastic layer is produced by laminating two repreg layers including the glass fiber cloth.
