Abstract
The relationship L1≦V(F1×ε1/2×100) is satisfied where a transmission path length between the interface 1 and the timing controller is L1, a propagating speed of electromagnetic waves in a vacuum is V, a frequency of a signal transmitted between the interface and the timing controller is F1, and a comparative dielectric constant of a transmission path medium between the interface and the timing controller is ε1. The relationship L2≦V(F2×ε21/2×100) is satisfied where a transmission path length between the timing controller and the signal driving portion is L2, a propagating speed of electromagnetic waves in a vacuum is V, a frequency of a signal transmitted between the timing controller and the signal line driving portion is F2, and a comparative dielectric constant of a transmission path medium between the timing controller and the signal line driving portion is ε2. Thus, the occurrence of EMI noise can be suppressed, and the implementation cost of a display apparatus can be reduced.
