    • A (liquid crystal display) LCD includes a pixel array and a gate driving circuit. The pixel array includes a plurality of first oxide thin film transistors, a first oxide thin film transistor of the first oxide thin film transistors with a shortest channel length having a first channel length. The gate driving circuit is coupled to the pixel array for driving the pixel array, and includes a plurality of second oxide thin film transistors. The second oxide thin film of the second oxide thin film transistors with a longest channel length has a second channel length. A ratio of the second channel length and the first channel length is greater than 1.5. By limiting the ratio of the second channel length and the first channel length, the aperture ratio of the display panel can be improved without deteriorating the operation stability of the LCD.
    • A(液晶显示器)LCD包括像素阵列和栅极驱动电路。 像素阵列包括多个第一氧化物薄膜晶体管,具有第一沟道长度的具有最短沟道长度的第一氧化物薄膜晶体管的第一氧化物薄膜晶体管。 栅极驱动电路耦合到像素阵列以驱动像素阵列,并且包括多个第二氧化物薄膜晶体管。 具有最长沟道长度的第二氧化物薄膜晶体管的第二氧化物薄膜具有第二沟道长度。 第二通道长度与第一通道长度之比大于1.5。 通过限制第二通道长度和第一通道长度的比例,可以提高显示面板的开口率,而不会降低LCD的操作稳定性。
