    • Projecting sections controlling alignment directions of liquid crystal molecules are provided on at least one of an active matrix substrate and a counter substrate. When viewed from a direction perpendicular to a surface of the active matrix substrate or of the counter substrate, an outline shape of the projecting sections is constituted by continuously arranging a plurality of unit patterns each having a side in parallel with the polarization axis of the first polarizing plate and a side in parallel with the polarization axis of the second polarizing plate. This makes it possible to provide a liquid crystal panel that performs better display with high contrast by reducing a light leakage during a black display period and by ensuring a light transmittance during a gray level display period and a white display period.

    • In a wiring figure pattern of a display panel, each wiring is separated into bands of optimal widths by slits of a constant width as a wiring figure pattern so that minimum light irradiation for curing a photocuring sealing material can be carried out without increasing the electric resistance of the wiring. The optimal width means a resistance such that light coming from both sides of the band cures the sealing material on the upper surface of the band without influencing the driving and display of liquid crystal. At a point where the width of wiring becomes two times or more of the optical width between the start point and end point of intersection of the wiring and the sealing material region, the wiring is divided by the slit. A first branch forms the band of the optimal width extending from the branch point to the end point, whereas the second branch extends to the end point and is spaced apart from the first branch by the width of the slit. At a point where the width becomes two times or more of the optimal width, the wiring is divided. Subsequently, branching is repeated until the end point is reached. A continuous triangle is formed in the slit at each branch, thus adjusting the width of the bands to have the optimal width.
    • 在显示面板的布线图形中,通过作为布线图形的恒定宽度的狭缝,将各布线分离成最佳宽度的带,从而可以在不增加电阻的情况下进行用于固化光固化密封材料的最小光照射 的接线。 最佳宽度是指使得来自带的两侧的光固化在带的上表面上的密封材料而不影响液晶的驱动和显示的电阻。 在布线宽度成为布线与密封材料区域的起点和终点之间的光学宽度的两倍以上的点处,布线被狭缝分割。 第一分支形成从分支点延伸到终点的最佳宽度的带,而第二分支延伸到终点并且与第一分支间隔开狭缝的宽度。 在宽度变为最佳宽度的两倍或更多的点处,布线被划分。 随后,重复分支直到达到终点。 在每个分支处的狭缝中形成连续的三角形,从而调节带的宽度以具有最佳宽度。

    • An object of the present invention is to provide a liquid crystal display device which is capable of preventing single-image prolonged-display screen burn while keeping an image constantly on display.The liquid crystal display device includes a liquid crystal panel provided with groups of pixel formation portions disposed in a matrix pattern, and a backlight which is capable of turning ON/OFF of lighting for each region which includes a predetermined number of scanning lines. Each frame period for an entered video signal is divided into a first sub-frame period and a second sub-frame period. In the first sub-frame period, the liquid crystal panel is supplied with a data signal based on the entered video signal as the scanning lines are selected. In the second sub-frame period a data signal based on a refresh data for prevention of screen burn is supplied. Each region as a unit of backlight ON/OFF state control is supplied with lighting when pixel formation portion group on the scanning lines served by the region are supplied with data signal based on the entered video signal while lighting is not supplied when data signal based on the refresh data is supplied.
