Liquid crystal box lens panel and liquid crystal display device

Abstract

The invention provides a liquid crystal box lens panel and a liquid crystal display device. The liquid crystal box lens panel comprises a first substrate, and an upper electrode is arranged on the surface of the first substrate; a second substrate is arranged relative to the first substrate; a first photo spacer is arranged between the first substrate and the second substrate to form a gap; edges of the first substrate and the second substrate are sealed to form a sealed area; the surface of the second substrate is provided with a metal trace in the sealed area, the surface of the metal trace is provided with a passivation layer with a via hole, and a transparent electrode penetrates through the via hole to be electrically connected with the metal trace; and a second photo spacer is arranged on the surface of the passivation layer and / or the surface of the upper electrode to reduce the width of a gap of the sealed area, and the gap of the sealed area is filled with a sealant. The invention has the following advantages: when a liquid crystal display panel production line is adopted to manufacture the liquid crystal box lens panel, the diameters of fiber balls are not increased; a sealant material is saved, and the discharge capability of a sealant spray nozzle of equipment is not increased; and the contact area between a liquid crystal and the sealant is reduced, and a puncture risk is reduced.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a lens panel of a liquid crystal cell and a liquid crystal display device. Background technique [0002] In the current mainstream naked-eye 3D display technology, liquid crystal lens technology has become an important development direction because it can flexibly realize the switching of 2D / 3D mode without significantly affecting the 2D mode display. The basis of liquid crystal lens technology is to simulate the light adjustment function of the microstructure lens so that pixels in different regions are projected into the left and right eyes respectively, so that images with parallax can be synthesized in the brain for a three-dimensional effect. [0003] figure 1 It is the structure of the conventional liquid crystal cell lens panel. see figure 1 As shown, a conventional liquid crystal cell lens panel includes a first substrate 10 , a second substrate 11 and a spacer 12...

AI Technical Summary

Problems solved by technology

[0004] Ordinary LCD cells are about 3.5 μm thick, and the liquid crystal cell lens panel requires at least 20 μm of liquid crystal cell thickness to ensure the lens effect. The thickness of the sealing area 14 of the liquid crystal cell lens panel is conventionally designed to match the display area of ​​the liquid crystal cell lens panel. The gap L is similar, so the liquid crystal lens will have the following disadvantages when it is produced on an ordinary LCD production line: (1) It consumes nearly 5 times more sealant materials; The diameter of the fiber ball 101 and the metal ball 100; (3) The contact area between the liquid crystal and the sealant becomes larger, and the risk of puncture increases
