Such a liquid crystal display device has a liquid crystal panel in which a liquid crystal panel is interposed between two adjacent substrates through a liquid crystal layer as an essential component and changes the alignment direction of the liquid crystal molecules in an electric field in the liquid crystal panel to realize a difference in transmittance do.

At this time, since the liquid crystal panel does not have a self-luminous element, a separate light source is required to display the difference in transmittance as an image. To this end, a backlight unit having a light source is disposed on the back surface of the liquid crystal panel.

On the other hand, the organic light emitting diode display device uses a self-luminous element, so that it is lightweight and thin because it does not require a backlight used in a liquid crystal display device which is a non-luminous element.

In addition, it is advantageous in terms of power consumption because it has superior viewing angle and contrast ratio compared with liquid crystal display device. It is able to drive DC low voltage and has fast response time. It is strong against external impact because its internal components are solid, I have.

As described above, a liquid crystal display device and an organic light emitting diode display device having non-target and excellent performance are widely used and more active research is being conducted.

On the other hand, the flat panel display requires a driver including an IC for controlling the driving. Generally, the driver is implemented through a printed circuit board (PCB).

Such a printed circuit board is divided into a gate printed circuit board connected to the gate wiring of the display panel and a data printed circuit board connected to the data wiring.

At this time, these printed circuit boards are connected to a first edge of the display panel and a second edge adjacent to the display panel through a connection member such as a flexible circuit board or a tape carrier package (TCP).

Accordingly, the width of the bezel is determined by the width NDA of the second non-display area NDA2 and d1 to cover the second non-display area NDA2 and d1.

As described above, the first and second non-display areas NDA1 and NDA2, particularly the first non-display area NDA1 occupy a wider area than the third and fourth non-display areas NDA3 and NDA4, It is causing the width to widen. As a result, there are limitations in implementing a narrow bezel.

On the other hand, pad electrodes and wirings (40b in FIG. 2A) (not shown) formed in the first and second non-display areas NDA1 and NDA2 of the first substrate G1 are made of a metal material, Even if the region is covered, the light inside is transferred to the pad electrode and the wiring of the metal to cause a light leakage phenomenon, or light is reflected to the pad electrode and the wiring of the metal to generate reflected light.

In particular, the first non-display area NDA1 of the first substrate G1 on which the gate driver is directly formed occupies a wider area than the second non-display area NDA2, and the metal pad electrode and wirings and the IC are included Therefore, the light leakage phenomenon and the reflected light generated in the first non-display area NDA1 serve as a factor for lowering the user's sensation.

3A and 3B, the flat panel display 100 includes a display panel 110 composed of a first substrate G1 and a second substrate G2 which are bonded to each other with a liquid crystal layer 133 interposed therebetween, And a backlight unit (BLU) positioned on the back side of the backlight unit.

The display panel 110 includes a first substrate G1 and a second substrate G2 to prevent leakage of the liquid crystal layer 133 interposed between the first and second substrates G1 and G2 facing each other, The first and second substrates G1 and G2 are attached together by including a seal pattern 142 printed along the outermost edge between the substrates G2 and may be called a liquid crystal panel.

The display panel 110 is divided into a display area DA for displaying an image and first to fourth non-display areas NDA1, NDA2, NDA3 and NDA4 which are formed around the display area DA and which do not display an image . The first non-display area and the second non-display area NDA1 and NDA2 include metal pad electrodes and a mounting area including a link wiring and an IC connected to the pad electrodes.

Although not shown, on the inner surface of the first substrate G1, a gate wiring, a data wiring, and a thin film transistor which intersect each other and define a plurality of pixel regions, and a pixel electrode 115 connected to the thin film transistor and formed for each pixel region are provided do.

On the inner surface of the second substrate G2 facing the first substrate G1, a color filter layer 135 including red, green, and blue color filter patterns corresponding to each pixel region and sequentially and repeatedly formed, And a black matrix (not shown) is provided corresponding to the periphery of the region.

A plurality of columnar patterned spacers (not shown) may be provided between the first substrate G1 and the second substrate G2 with a liquid crystal layer 133 interposed therebetween. The patterned spacers The first substrate G1 and the second substrate G2 are provided such that both ends thereof contact the first and second substrates G1 and G2, respectively, thereby maintaining a cell gap between the first substrate and the second substrates G1 and G2. At this time, the patterned spacers (not shown) may be provided one by one for each pixel region, or may be formed only in correspondence with the pixel region where any one of the red, green, and blue color filter patterns is formed.

A backlight unit (BLU) for supplying light to display the difference in transmittance as an image is disposed on the back surface of the second substrate G2. A backlight unit (BLU) is disposed on the outer surface of the first and second substrates G1 and G2, The first and second polarizing plates 119a and 119b are selectively attached.

The display panel 110 according to the present invention having the above-described structure has a structure in which a face viewed by the viewer is a first substrate G1 in a state in which the conventional display panel (10 in Figs. 2A and 2B) Is disposed so as to be the outer surface of the first substrate G1.

Hereinafter, the non-display region of the display panel according to the present invention will be described in more detail with reference to FIGS. 3A and 3B.

3A, a gate IC 140a, a plurality of gate pad electrodes, and a gate link wiring 140b connected to the gate IC 140a, respectively, are formed in the first non-display area NDA1 of the inner surface of the first substrate G1 A gate driver 140 is provided.

The gate IC 140a of the gate driver 140 includes a built-in shift register, receives a control signal from the outside, sequentially supplies a driving signal of a thin film transistor (not shown) to a gate wiring (not shown) (Not shown) to turn on.

A light shielding pattern 170 is formed on the outer surface of the first substrate G1 corresponding to the first non-display area NDA1 on the inner surface of the gate driver 140. [

The shielding pattern 170 overlaps the gate driver 140 formed in the first non-display area NDA1 of the first substrate G1 and the metal pad electrode 140b including the gate IC 140a, Which is formed by applying a phase change ink through an aerosol jet system.

Here, the phase change means that the state of the material changes according to the temperature condition. The phase change ink maintains a high viscosity state at a normal room temperature, but is maintained at a temperature of 40 to 80 When heated to a temperature of ㅀ, the viscosity changes to a low state, and after being sprayed onto the substrate, it forms a shape by solidifying in a certain form within several ms.

Such phase change inks include phase change materials, light or heat curing materials, and black pigments such as carbon black.

Here, since the phase change ink does not need to contain a solvent-like substance used in the photolithography process, it can be cured at a temperature of 100 ° C or less, thereby applying a low-cost UV curing apparatus or applying a low- . At this time, it is also possible to include a certain amount of solvent in the phase change ink according to the present invention. In this case, the dischargeability of the aerosol jet system can be improved.

On the other hand, if the solvent contains more than a certain amount, the optical density (OD) value indicating the opacity of the material may be lowered.

Since the amount of the solvent and the optical density are inversely proportional to each other, it is preferable that the optical density of the light-shielding pattern 170 according to the present invention is 4.0 or more by not including the solvent or including a very small amount of solvent. The light blocking pattern 170 absorbs light from the inside or the outside, thereby blocking light leakage and the generation of reflected light.

This light shielding pattern 170 is formed through ink ejection through the air pressure of the aerosol jet system.

Here, an aerosol-jet system not shown in the drawings is described. The aerosol jet system includes a vacuum chamber, and a heater and a droplet are aerosol-jetted in a vacuum chamber. And a substrate support provided under the nozzle assembly to which the substrate is mounted. Thus, when the phase change ink maintaining solid state at normal temperature is filled in the vacuum chamber, the heater heats and melts the solid phase change ink in the vacuum chamber to the melting point or higher. The melted liquid phase-change ink is atomized to form droplets of high density and this droplet is transferred to the head of the nozzle assembly by a carrier gas, for example, an annular sheath gas. and a high-density liquid droplet is aerosolized by the pressure difference at the nozzle of the head portion and is sprayed onto the substrate. At this time, the line width of the formed light-shielding pattern 170 can be formed within the range of 10 to 1 cm, and the thickness can be formed within the range of 100 nm to 10 μm.

Such line widths and thicknesses are possible through an aerosol jet system, and in particular, the aerosol jet system enables to form a light shielding pattern 170 having a line width of 1 cm, a thickness within a range of 100 nm to 1 μm, and an optical density of 4.0 or more. Accordingly, the light shielding pattern 170 corresponding to the first non-display area NDA1, which is generally formed to be 1 cm or less, can be formed continuously on a large-area substrate at one time. Further, it has an advantage that a light shielding pattern 170 can be formed by applying a small amount of phase change ink.

4, the light-shielding pattern 170 may be formed of a single line, but is not limited thereto. The light-shielding pattern 170 may include a plurality of stripes having a thickness in the range of 100 nm to 1 μm and a line width in the range of 10 μm to 1 cm. May be formed. It is also preferable that the light-shielding pattern 170 is formed so that the optical density value is 4.0 or more.

The light shielding pattern 170 formed through the aerosol jet system is applied to the flat panel display 100 according to the present invention so that the first substrate G1 is disposed on a surface viewed by the user for viewing an image, Even when the light is incident toward the first substrate G1, external light can not be transmitted through the light shielding pattern 170. Even when internal light is transferred to the metal materials of the gate driver 140, So that it can not be transmitted to the outside. Therefore, the light leakage phenomenon and the reflection light generation can be prevented.

In the meantime, although it is shown that the step is formed when the first polarizing plate 119a is attached to the upper part of the shielding pattern 170, since the shielding pattern 170 is formed to have a thickness within the range of 100 nm to 10 mu m, .

Referring to FIG. 3B, the data printed circuit board 118 is connected to the inner second non-display area NDA2 of the first substrate G1 through the connecting member 116. [ Here, the connecting member 116 may correspond to a tape carrier package (TCP) or a flexible printed circuit board (FPC).

At this time, the data printed circuit board 118 is bonded to the back surface of the backlight unit BLU by bending the connecting member 116 in the module process. That is, the connection member 116 is bent so as to surround the second substrate G2 and the outer surface of the backlight unit BLU disposed on the backside thereof.

That is, the data printed circuit board 118 is positioned on the back surface of the backlight unit BLU through the connecting member 116 in the second non-display area NDA2 of the first substrate G1, thereby eliminating the bezel .

2B) of the display panel (10 in FIG. 2B) is located at a lower portion, and a second substrate (FIG. 2B) And the backlight unit (BLU in FIG. 2B) is disposed on the back surface of the first substrate (G1 in FIG. 2B). 2B) is connected to the first substrate (G1 in FIG. 2B) via a connecting member (16 in FIG. 2B) and the connecting member (16 in FIG. 2B) The connection member (16 in FIG. 2B) is exposed to the outside by d1 as the substrate is bent through the side surface of the substrate (G1 in FIG. 2B), so that the width of the bezel is equal to the sum of the widths of the second non-display areas NDA2 and d1 NDA).

However, in the liquid crystal display device 100 according to the present invention, the display panel (10 in Fig. 1) is reversed so that the first substrate G1 is disposed on the upper side viewed by the user, 1 substrate G1 on the inner surface of the backside unit BLU through the connecting member 116 in the second non-display area NDA2. That is, since the connecting member 116 is bent to surround the second substrate G2 beneath the first substrate G1 and the outer surface of the backlight unit BLU disposed on the backside thereof, the connecting member 116 can eliminate the conventional d1, 2 non-display area NDA2 is also hidden through the inner surface of the first substrate G1, the bezel can be eliminated and the screen viewed by the user can be widened.

3B, only the substrate surface of a substantially transparent material is exposed on the outer surface of the first substrate G1.

In this manner, the display panel 110 is inverted to use the first substrate G1 as the front surface of the flat panel display device 100 and the light shielding pattern 170 on the outer surface corresponding to the first non-display area NDA1 A borderless flat panel display device can be realized as shown in FIG.

That is, the flat panel display 100 according to the present invention includes a component for covering the non-display area on all edges by applying a light shielding pattern 170 to prevent light leakage and reflected light due to a gate driver occupying a wide area, It has the advantage of completely eliminating the bezel such as the top cover.

Although not shown, the shielding pattern 170 may be formed on the outer surface of the first substrate G1 corresponding to the second non-display area (NDA2 in FIG. 3B) where the data pad electrode and the data link wiring are formed. In this case, the light leakage phenomenon due to the data pad electrode and the data link wiring and the reflected light can be blocked. Therefore, the light leakage phenomenon and the reflected light due to the metal pad electrode and wiring can be completely cut off by the flat panel display device.

It is apparent that the shielding pattern according to the present invention can also be applied to a case where a gate driver is formed through a gate printed circuit board .

Also, a light-shielding pattern according to the present invention can be applied to a case where a gate and a data printed circuit board are connected to an edge of a first substrate via an FPC.
