I want to make an image white on keypress in pygame

I am trying to create a Tic tac toe game in pygame. I want to display an image on the screen when a key is pressed. Pressing the escape key quits the game, but when I press key 1 the image goes black, nothing happens. this is the code

import pygame
from pygame.locals import (
    K_1,
    K_2,
    K_3,
    K_4,
    K_5,
    K_6,
    K_7,
    K_8,
    K_9,
    K_ESCAPE,
    K_UP,
    KEYDOWN,
    QUIT
)
clock = pygame.time.Clock()
pygame.init()

# Constants
display_width = 300
display_height = 300
white = (255, 255, 255)
black = (0, 0, 0)
run = True

# Creating game screen
display = pygame.display.set_mode((300, 300))
pygame.display.set_caption("Tic Tac Toe Game")
display.fill(white)

# importing images to pygame
circle_image = pygame.image.load("resizedimage1.png")
cross_image = pygame.image.load("resizedimage2.png")

# main game loop
while run:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False
        elif event.type == KEYDOWN:
            if event.key == K_ESCAPE:
                run = False
            elif event.key == K_1:
                display.blit(cross_image, (10, 10))
                clock.tick(30)

    display.fill(white)
    pygame.draw.line(display, black, (100, 0), (100, 300))
    pygame.draw.line(display, black, (200, 0), (200, 300))
    pygame.draw.line(display, black, (0, 100), (300, 100))
    pygame.draw.line(display, black, (0, 200), (300, 200))
    pygame.display.update()

pygame.quit()
