Abstract
A liquid crystal display (LCD) panel simplifying its testing and manufacturing. The LCD panel includes (formed on a substrate) gate lines, data lines, and pixels including pixel transistors. The LCD panel further includes a plurality test transistors (e.g., data test transistors for driving the odd and even data lines) formed in a package region of a driving IC (integrated circuit) configured to drive the data lines. The plurality of test transistors may be selectively activated (turned ON) during testing before the driving integrated circuit (Driver IC package) is attached (e.g., fixed) to the driving IC package region. The LCD panel may further include a plurality of gate test transistors configured to drive the odd and even gate lines.
