ABSTRACT:
An LCD device that is able to remove the luminance unevenness on the display area while preventing the short-circuit and open-circuit is provided. The LCD device includes a liquid-crystal panel having first and second substrates and liquid crystal filled in a space formed between the first and second substrates. Pixel electrodes are formed on the first substrate and are arranged in a matrix array in a display area of the panel. Driving lines are formed on the first substrate in the display area and are electrically connected to the respective pixel electrodes. Terminal areas are formed on the first substrate outside the display area. Driver ICs are mounted on the first substrate outside the display area and are electrically connected to the corresponding terminal areas. Connection lines are formed on the first substrate outside the display area and are electrically connected to the respective driving lines and the corresponding terminal areas. The resistance difference of any adjacent two ones of the connection lines is lower than a threshold resistance value at which a man is able to recognize the luminance unevenness on the display area.
