NOISE REDUCING STRUCTURE AND LIQUID CRYSTAL DISPLAY DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide noise reducing structure more effectively reducing electromagnetic disturbance and electromagnetic radiation of a circuit substrate by increasing contact pressure of a conductive sealing material and improving electric connectivity of the conductive sealing material. SOLUTION: The noise reducing structure is provided with a metal frame placed opposite to the circuit substrate holding a gap between a metal pattern region formed on the circuit substrate in a liquid crystal display device and itself. The metal frame is brought into contact with the conductive sealing material inserted into the gap and is electrically connected to the metal pattern region. At least a contact surface of the metal frame brought into contact with the conductive sealing material is treated so as to have 3-10μm surface roughness Rmax value.
