Display driving device, semiconductor device and liquid crystal display apparatus

A display driving device, comprising:

• a bias circuit that generates a bias signal;
• a plurality of amplifier stages;
• a plurality of output stages respectively connected to the plurality of amplifier stages;
• a first bias signal line connected to the bias circuit and the plurality of amplifier stages;
• a second bias signal line connected to the bias circuit and the plurality of output stages;
• and
• a short circuit line disposed in the bias circuit and short-cutting the first bias signal line and the second bias signal line, wherein:
• the short circuit line is shielded;
• the plurality of amplifier stages are controlled by the bias signal supplied from the bias circuit via the first bias signal line to respectively amplify input display signals respectively supplied to the amplifier stages;
• and
• the plurality of output stages are controlled by the bias signal supplied from the bias circuit via the second bias signal line to respectively supply output signals of the plurality of amplifier stages to a plurality of display elements.
