Embodiment Construction
[0032] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are only for reference The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In the figures, structurally similar elements are denoted by the same reference numerals.
[0033] The present invention is aimed at the existing display panel, because the starting end and the end of the conductive particle coating will be unevenly coated, it needs to be reserved when forming the alignment pad, and the improper formation position of the alignment pad will easily lead to cutting of the thin film transistor substrate When the residual material...

The present invention provides a display panel, comprising a color film substrate, a thin film transistor substrate and a liquid crystal layer; a first transparent conductive layer is arranged on the color film substrate; A conductive portion electrically connected to the first transparent conductive layer; wherein, the thin film transistor substrate has a cutting side, the pad group includes a plurality of alignment pads, the conductive portion is arranged along the direction of the alignment pads, and the cutting The distance between the first alignment pad with the largest side distance and the cutting side is greater than or equal to the length of the conductive portion. By designing and arranging the positions of the alignment pads on the thin film transistor substrate, the distance between the first alignment pad and the cutting side is greater than or equal to the length of the conductive part, so as to avoid the abnormal peeling of the cutting residue, and ensure that When coating the conductive portion, sufficient length is reserved, and at the same time, it is possible to prevent the alignment pad from affecting the cutting of the thin film transistor substrate.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a preparation method thereof. Background technique [0002] With the rapid development of LCD devices, the demand for transparent conductive film (ITO) products is also increasing. ITO has high electrical conductivity, high visible light transmittance, high mechanical hardness and good chemical stability. At present, the LCD panel display industry uses laser cutting of the ITO film on the color filter substrate for the new technology, and divides the ITO into different areas so that the ITO in different areas can input different signals. like figure 1 As shown, in the large-size LCD and mixed cutting technology of different sizes, the thin film transistor substrate is cut to expose the needles on the color filter substrate, and the signal is supplied from the color filter substrate side. The signal input H / L, the thin film transistor substrate side The sig...
