A thin film transistor substrate includes: a substrate; a thin film transistor and a capacitor formed on the substrate; and a protective film for protecting an electrode on a back surface side of the capacitor when an electrode on a front surface side of the capacitor is cut by irradiation with laser light, the protective film being disposed at such a position as to enclose a corner part of the electrode on the front surface side between the electrode on the front surface side and the electrode on the back surface side of the capacitor.

Thin film transistor substrate, defect repairing method therefor, and display device

A battery charging apparatus for charging the electricity from a current source to a cell includes a variable resistor in parallel with the cell, a cell voltage detection unit for detecting the current voltage value of the cell and a comparator for comparing the current voltage value to a pre-set voltage value. The resistance value of the variable resistor is controlled responsive to the results of comparison so that the current from the current source is caused to flow through both the cell and the variable resistor with progress in the charging of the cell. The current is prevented from flowing through the cell when the cell is fully charged, so that overcharging is eliminated. If plural cells are charged in series, the control operation of not causing the current to flow through the fully charged cell can be carried out for each of the cells, so that integrated charging may be continued until all of the cells are fully charged thus shortening the cell charging time.
