Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0026] Such as figure 1 , 2 As shown, a liquid crystal display device includes a liquid crystal panel, the liquid crystal panel includes an upper substrate 10a and a lower substrate 10b, the upper substrate 10a and the lower substrate 10b are opposite to each other, and a negative liquid crystal layer with Δε<0 is interposed therebetween 12. The upper polarizer 14a and the lower polarizer 14b are attached to the outside of the upper substrate 10a and the lower substrate 10b respectively, and the absorption axis 16a of the upper polarizer and the absorption axis 16b of the lower polarizer are parallel to each other. A layer of biaxial compensation film 18b is sandwiched between the lower substrate 10b and the absorption axis of the lower polarizer 14b, and the slow axis 20 of the compensation film is perpendicular or parallel to the absorption...

Abstract

The invention discloses a liquid crystal display (LCD) panel and an LCD device. The LCD panel comprises an array base plate, wherein the bottom of the array base plate is provided with a lower polaroid, and the LCD panel is provided with a compensating film only between the array base plate and the lower polaroid. The LCD panel is provided with the compensating film only between the array base plate and the lower polaroid, single-layer compensation is adopted, and the compensating film does not exist between a multi-color light filter plate and an upper polaroid, so that one layer of compensating film is eliminated, the optimization of the view angle performance of the LCD device is guaranteed, at the same time, the material of the compensating film is saved, and the cost of the LCD device is reduced. The compensating film is adhered between a lower base plate and the lower polaroid, so that the reworking probability is reduced, and the waste of the compensating film is reduced.

Description

technical field [0001] The invention relates to the field of liquid crystal display, and more specifically, to a liquid crystal panel and a liquid crystal display device. Background technique [0002] A liquid crystal display (LCD) includes an upper substrate and a lower substrate, and a transparent electrode exists on the opposite inner side of the substrate. A layer of liquid crystal molecules is sandwiched between the two substrates. The liquid crystal display controls the orientation of the liquid crystal molecules through the electric field, changes the polarization state of the light, and realizes the purpose of display by using the polarizer to realize the penetration and blocking of the light path. According to different initial arrangements of liquid crystal molecules, liquid crystal displays can be classified into TN type, IPS type, VA type, etc. Among them, the VA type has the characteristics of high contrast and wide viewing angle because the initial liquid cry...
