Ink droplets may be directly applied onto the glass substrate 53 to form each color element.

FIG. 6A shows a glass substrate 1 having a black matrix 2 which constitutes a light transmitting portion 9 and a light shielding portion 10.
Is shown. The black matrix 2 is not always necessary. First, on the substrate 1 on which the black matrix 2 is formed, although the ink itself is poor in ink receptivity, it becomes an ink-philic ink under a certain condition (for example, light irradiation, or light irradiation and heating), and under a certain condition. A resin composition having the property of hardening is applied, and prebaking is performed as necessary to form the resin composition layer 3 (FIG. 6B). The resin composition layer 3 can be formed by any coating method such as spin coating, roll coating, bar coating, spray coating, and dip coating, and is not particularly limited.

Next, the resin layer on the light transmitting portion 9 is preliminarily subjected to pattern exposure using the photomask 4 to partially make the resin layer ink-philic (FIG. 6 (c)). An ink-philic portion 6 and a non-ink-philic portion 5 are formed on the layer 3 (FIG. 6D).

After that, the ink jet method R
Ink of each color (red), G (green), and B (blue) is discharged onto the resin composition layer 3 to be colored at once (FIG. 6E), and the ink is dried if necessary. Examples of the inkjet method include a method using thermal energy and a method using mechanical energy, and any of these methods can be suitably used. The ink to be used is not particularly limited as long as it can be used for ink jet. The coloring material of the ink is required for each pixel of R, G, and B from various dyes or pigments. A transmission spectrum suitable for the transmission spectrum is selected as appropriate.

Next, the colored resin composition layer 3 is cured by light irradiation or light irradiation and heat treatment, and a protective layer 8 is formed if necessary (FIG. 6 (f)). In order to cure the resin composition layer 3, conditions different from the conditions in the previous ink-affinity conversion process, for example, increasing the exposure amount in light irradiation, tightening heating conditions, or using light irradiation and heat treatment together And the like.

7 and 8 are flowcharts showing a color filter manufacturing process in the color filter manufacturing apparatus of the present embodiment. A control program for executing this process is stored in the ROM 67 of FIG.
Run under the control of Here, in order to simplify the explanation, in FIG. 4, it is assumed that the nozzles of the head 55 have the same distance as each color element and the width of each color element in the X direction is substantially equal to the diameter of one ink droplet. To do.

When the manufacture of the color filter is instructed, first, in step S1, the number of dots (n) forming one color element on the color filter is input from the operation unit 60.
According to this value n, for example, as shown in FIG. 5, one color element is formed with a designated number of dots (in FIG. 5, n
= 4). Next, in step S2, the YXθ table 52
Then, the inkjet head 55 is positioned. At this time, an R counter, a G counter, a B counter, and a color element counter (all of which are provided in the RAM 68) described later are cleared to "0". And step S
At 3, the stage controller 71 is driven to start moving the XYθ table 52 in the Y direction.

In step S4, it is determined whether it is time to eject ink from the R head, that is, whether the corresponding nozzle of the R head has reached the position where the color element of R color is formed. This is determined based on the initial position of the XYθ table 52, the amount of movement thereof, the position of the head of each color of the inkjet head 55, and the nozzle position thereof. When it is determined that the ink ejection timing from the R head has arrived in this way, the process proceeds to step S5, and the ejection control unit 70 ejects ink droplets from the corresponding plurality of nozzles of the R head to form one ink for the R color element. Drops are applied, and the R counter that counts the number of ink drops applied to one R color element is incremented by one.

Next, in step S6, the aforementioned step S
Similarly to step 4, it is determined whether or not the G head has come to the position of the element of G color, and if so, the process proceeds to step S7, and the corresponding nozzle in the G head is selected in the same manner as step S5 described above. An ink droplet is ejected by using the G color element, and the G counter that counts the number of ink droplets applied to one G color element is incremented by one. Further, also in step S8, it is similarly determined whether or not it is time to eject ink droplets from the B head.
If so, the process proceeds to step S9 and the above-mentioned step S5.
Alternatively, as in S7, an ink droplet is ejected from the corresponding nozzle of the B head to apply 1 dot of ink to the B color element, and the number of ink droplets applied to one B color element is counted B Increment the counter by 1.

Thus, the process proceeds to step S10, and it is checked whether or not an abnormality has occurred in the device based on the signal from the sensor 61 or the discharge failure detection device 57 described above. When no abnormality has occurred, the process proceeds to step S11 to check whether the creation of all color elements is completed. If not completed, step S1
The procedure proceeds to step 2 and checks whether or not there is a counter whose count value is (n) among the R, G, B counters, and if there is, increments the color element counter of the color corresponding to that counter by +1 and The counter of is cleared to "0".
As described above with reference to FIG. 2, it may be determined whether or not there is an emergency stop button of the device or an instruction from an external device.

On the other hand, if an abnormality occurs in step S10, the process proceeds to step S14, and among the R, G, B counters,
It is checked whether there is at least one counter whose count value is not "0" or "n", that is, whether there is a color element in the process of forming one color element. If it exists, step S15.
Then, in order to form the rest of the color element corresponding to the counter, the rest of the color element is formed in the same manner as in steps S3 to S9 described above. When there are no more color elements in the process of being formed in this way, the process proceeds to step S16, and the number of color elements formed for each nozzle of the inkjet head 55 is stored in the RAM 68. And step S17
, The operation of the apparatus is stopped, and in step S18 XYθ
The stage 52 is retracted.

Next, in step S19, the cause of the abnormality is removed by the operator, and when the restart of the operation is instructed, the process proceeds to step S20, in which the XYθ table 52 or the ink jet head 55 is moved to a predetermined position and preliminary ejection is performed. I do. Then, the process proceeds to step S21, and step S1
6, the stage controller 71 is driven to position the XYθ table 52 based on the number of color elements stored in the RAM 68, and the process returns to step S3 to form the remaining color filter color elements. Proceed to.
